I'm sorry to say that I was seeing a lockup regularly yesterday but didn't know that I was supposed to be doing extensive logging etc. :( It seemed to happen quite often if I got some kind of a crash when I was trying to write to the database and then tried again later. As if the lock wasn't properly released after the crash. I can't reliably reproduce it but I'll fiddle when I get a chance. Paul Prescod Jim Fulton wrote:

Zopsters,
I have just experienced a lockup just like beta4 in beta5!
This happened on the beta zope site on Tuesday. It hasn't happened since.
Anyone else privy to this?
I'm curious too. Has anyone else seen this?
Specifically, has anyone else had a problem with their Zope site becomming completely unresponsive? If so, please contact me ASAP. Feel free to call the number below.
I would *love* to find a site for which this happens with some regularity so that I can nail whatever's causing this.
BTW, *please* make sure that logging is turned on. See doc/LOGGING.txt in the Zope distribution.
If your site does become unresponsive, here are some things I'd like you to do:
- Send me both the logger log and the hit log (zipped or gzipped).
- If this is on Uniz, send me output of a verbose ps command ('ps auwwx' or 'ps -elf').
- If running on linux, send me the output of:
strace -p <pid_of_zope_process> 2>/tmp/crazy_zope.log
(send me the crazy_zope.log).
- If you have FTP enabled, try:
ftp hostname port
where hostname and port are the machine and port you have ZServe servng FTP on. I want to see if you get any sort of response after making the connection. That is, I want to see if the medusa part of ZServer is responding.
- If you have the monitor enabled, have a plain text superuser password, and you are running on Unix, please try connecting to the monitor:
python ZServer/medusa/monitor_client.py hostname <password>
Is the monitor responding? If so, try:
import Zope print Zope.DB._pools[0]
If you are running beta 6:
print Zope.DB.connectionDebugInfo()
and send me the output. :)
