Hi, just a short update: neither our production server nor the testing environment have exhibited any crashes lately.
We still have the java printing api application (the one using BIRT) configured to access the testing system. So that explains why the production system does not crash any more. The testing system hardly gets any print jobs at all. So I guess for the server to crash we need both at least a moderate load of regular print jobs and an application accessing the printer list or details (such as Firefox or BIRT). I haven't had much time in the last couple of weeks to look into this, and I'll be out of the office for most of the next months, so I won't be able to work on this for the next couple of weeks.

Apport does not support reporting these crashes. I think the crash is due to my having a saved Firefox session with Cups' administration window (http://localhost:631/admin) in it. The crash seems to occur when this session is restored as part of the session restore when I log in to my desktop environment. I have turned on debug-logging and can see the following: D [25/Jan/2010:08:57:16 +0100] cupsdReadClient: 11 GET /images/cups-icon.png HTTP/1.1 D [25/Jan/2010:08:57:16 +0100] cupsdSetBusyState: Active clients D [25/Jan/2010:08:57:16 +0100] cupsdAuthorize: No authentication data provided.

Make sure your favorite browser is set to restore the last session on reload. 1) Load http://localhost:631/admin in your favorite browser. 2) Restart your computer. 3) Log in to your desktop environment. Expected result: The CUPS administration window should be loaded in your browser. Actual result: The CUPS administration window fails to load. The browser says: "The connection to the server was reset while the page was loading." It is not consistently reproducible, but I would say I see a failure rate of 80 %. It happens on both of my test machines.
