>-bash-2.05b$ ps-ef|grep python >-bash: ps-ef: command not found Actually here you type the wrong command, that's why you got "comand not found". You have to type "ps -ef|grep python" (a space is needed between "ps" and "-ef"). >-bash-2.05b$ killall python > but killall python did the trick. However you have to keep on mind that it doesn't kill only zope. It will kill other applications that are currently using python on that moment. For example: on Gentoo linux you have the "emerge" command to install packages. This is a python script and it will be killed as well if you do a "killall python", so, you had better see the output of "ps -ef|grep python" in order to kill the correct proccess, or, as other people said, use the "zopectl" script.

stopping zope?
by Aaron 26 Apr '04

26 Apr '04

I fought to get zope and plone installed and after much fighting succeeded, but now I am stuck with zope running and I need to stop it. I see that in my version of zope 6.2.3 there is stop in the root directory but I can't figure out how to use it and what to tell it to stop. I am using zopes server not apache or another server. I tried the zopebook but didn't find it. If someone could tell me how to kill a running zope or at least point me to the documentation it would be most appreciated Thanks Aaron

Dennis, Yup, I'm aware of all those issues. I'm due for an OS upgrade, and the 2.6 kernel is definitely in the plan precisely because of that feature. Hardware upgrades are harder to come by, but single-cpu will also be part of the requriements! In the mean time I think I figured it out (Time will tell.): I have a type class that caches some infromation in attributes, but when it's out of date it needs to get some of it from an FTP server. Apparently this feature is broken right now ... At first I noticed it was using a bad path, so I fixed that, but that still didn't help. I'm guessing something's change related to the FTP server and I wasn't notified. So I've disabled it entirely, because you know, it's saturday and gorgeous outside! Of note, Python 2.3 now supports socket timeout, something I've been wanting for a while, precisly because I was worried something like this could occur. I'll look after it all later. Many thanks to those who took the time to help on a week-end day, it was very helpful, and sorry to add traffic to the list, I work best when I'm thinking outloud :) Cheers, J.F. -----Original Message----- From: Dennis Allison [mailto:allison@sumeru.stanford.EDU] Sent: April 24, 2004 5:04 PM To: Jean-Francois.Doyon(a)CCRS.NRCan.gc.ca Cc: chrism(a)plope.com; zope(a)zope.org Subject: RE: [Zope] ZServer stops responding !? Help !? I wonder if you are not seeing a threading problem. Python has a single global interpreter lock ("GIL") and there are many interactions with schedulers that I do not fully understand. On my system(s) I run dual Athlon machines with 4GB of memory and have occasionally seen unexplained behavior others have attributed to theading conflicts and the GIL. Most 2.4 kernels do not support CPU affinity, but that's the right solution. CPU affinitiy is available with the 2.6 kernels and with RH9. but RH9 has its own problems, now mostly fixed.

Dennis, I'm using a 4 CPU machine PIII's at 700Mhz each, with 2 GB of RAM. (Dell PE6400) I've got the check interval at 200 (Pystones/50, as I once saw somewhere). I runs very fast the rest of the time though :) As tyime goes by I'm compiling some data as to what the server is doing, and I'm focusing on one particular content type. This type does avariety things depending on the condition. The "simplest" is that it does nothing particular, just uses it's attributes and methods. In one case, it could run a local system command using os.popen() ... And in the really worst case, it starts an FTP connection. To a server local to our shop, but that I don't control. I'm wondeing if there's problems with the FTP connection or the system call maybe in some circumstances or for specific instances. Maybe osme "bad data" gets returned ? Personally I would tend to look more towards the network I/O as a potential source of "blocking" ... Anybody the intricacies of how the network I/O is handled in Python 2.3 and/or Zope 2.7 ? Any differences with previous versions ? The hunt continues ... Much thanks to all who are helping !

Max, You mean needing to register a signal handler ? I thought Zope 2.7 had all that included now ? Also I use zopectl and zdaemon so it detaches from the console...

I don't know if Zope 2.7 still needs to be started with a nohup??

ZServer stops responding !? Help !?
by Jean-Francois.Doyon＠CCRS.NRCan.gc.ca 24 Apr '04

24 Apr '04

G'day, I've got a rather bizarre but catastrophic problem. ZServer seems to stop responding. Sometimes it does so after days of running, sometimes after a few seconds or minutes of uptime. I know it's ZServer because I can talk to the monitoring port without problem. Also, the apache processes just pile up up to the limit allowed, suggesting the proxying is not getting replies from the downstream server. The strange thing is the cause seems to be occacional, or vary. For hours on end I can sit there and restart it, and within minutes it stops responding ... Then suddenly the problem "disappears", I restart it, and I wait .... and nothing happens, it just keeps running. Nothing else abnormal is going on the server so far as I can tell, there is very little memory swapped, and the CPU usage is not abnormally high. I used to have this problem very very rarely in the past, but since I upgraded to Zope 2.7, it seems to have gotten much worse :( I tried accesing the DebugPanel from the monitor, but can't seem to get it to do anything useful ... I don't know where else to look to find the cause of this. This causes serious uptime problem on our main, high traffic site, which is Very Bad. I'm on RedHat 7.3 (fully patched) Python 2.3.3 (custom compiled) Zope 2.7 CMF 1.4.x (I forget ... the latest!) Psycopg (Latest also) And a variety of other products. Thanks, J.F.

I'm trying to install Zope 2.7 on Debian. I'm using the following software: python 2.3.3 gnu make 3.80 gcc 3.3.3 I'm running the following configure command as a non-root user (tom): ./configure --prefix=/opt/Zope-2.7 The /opt/Zope-2.7 directory exists, with an owner and group of "tom". I don't get any errors when I run "configure". It says that I have the "optimum version of python". However, run I run "make" as user tom, I get hundreds of errors and warnings, and I finally end with the following error: error: command 'gcc' failed with exit status 1 make: *** [build] Error 1 The errors seems to start the with the following line: gcc -pthread -fno-strict-aliasing -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -fPIC -I/tmp/Zope-2.7.0/lib/Components/ExtensionClass/src -I/usr/include/python2.3 -c AccessControl/cAccessControl.c -o /tmp/Zope-2.7.0/build-base/python-2.3/build-temp/AccessControl/cAccessControl.o This is the only time that gcc is called before the program crashes. Also, here are the last couple of lines that I get before make crashes (which look just like the 200 lines before them): AccessControl/cAccessControl.c:2237: error: initializer element is not constant AccessControl/cAccessControl.c:2237: error: (near initialization for `RestrictedDTMLMixinType.methods.link') AccessControl/cAccessControl.c:2237: error: initializer element is not constant AccessControl/cAccessControl.c:2237: error: (near initialization for `RestrictedDTMLMixinType.methods') error: command 'gcc' failed with exit status 1 I found someone else who was getting the same errors online (http://www.linuxquestions.org/questions/showthread.php?s=&forumid=18&thread…) However, this guy was trying to compile Zope 2.7 with python 2.3.1. I'm really stuck. Any help that I could get would be greatly apprecaited! Tom Purl
