Internal server error
Hi everyone, I've started seeing an intermittent error message on my site. It's an 'Internal Server Error' and I can't seem to correlate it with anything specific. So far, reloading whatever the page was has worked. Occasionally now, with no error reported, random graphics don't load. Again, reloading the page has always displayed them fine. This happens, for example, on the management screen. One time, the icons for DTML methods don't show up. Later it might be the folder icons. This is puzzling and a bit troubling. There doesn't seem to be anything unusual in the logs. Is this a sign of a corrupted ZODB? BTW, stopping and restarting Zope doesn't seem to have any affect on this intermittent problem. -Tim -- Timothy Wilson | "The faster you | Check out: Henry Sibley H.S. | go, the shorter | http://slashdot.org/ W.

The message "Internal Server Error" many times comes from a webserver that is frontending Zope... are you using Apache or another webserver in front of Zope or are you just using ZServer? Timothy Wilson wrote:

Although I can't comment on the original message, because I simply don't understand what could be causing the intermitted Internal Server Errors other than a corrupt ZODB (have you looked in the Utilities directory. Running bbb.py might give you some insight into what is causing the problem if it is a ZODB problem), I can say that I have experienced this when accessing a non-existent object via XML-RPC on a Zope installation running ZServer and NOT an external HTTP server. Basically, I misspelled the object I was trying to request and it sent back an error formed something like: Internal Server Error(404 Not Found) Or something to that effect... which seems to me that either two errors are somehow occurring and combining (an examination of the ZServer code says that this shouldn't happen and a general knowledge of HTTP servers also supports that theory) or something else is going on... duh! Now, when I access the same misspelled object via an HTTP client, I get the Zope error screen and just a 404 error. I just thought I would contribute and let people know that it's not just happening with external servers and to see if anyone knows why this error occurs under XML-RPC.

I'm using Apache w/ Zope for my pages. Unfortunately, things have gotten worse. Zope actually crashed not too long after I first experienced the problem. I SSHed into the system to poke around and found that it left a python process running that I've been unable to kill. [root@www utilities]# ps ax | grep python 5495 ? D 0:00 /usr/local/bin/python/usr/local/src/Zope-2.1.2-src/ I can restart Zope even with that old process there, but I would like to get rid of it before I go too far. I looked at bbb.py in the /utilities directory, but it says that it only works with ZODB2. Is there something similar for Zope 2.x? -Tim -- Timothy Wilson | "The faster you | Check out: Henry Sibley H.S. | go, the shorter | http://slashdot.org/ W.
