Public bug reported:
Binary package hint: cupsys
On my print servers i expirienced unpredictable printer queue hangs.
The printers just stopped printing, but in the web interface there was
nothing special shown. I started tracing down the problem and found
following:
d [23/Jul/2007:06:02:10 +0000]
cupsdStartProcess("/usr/lib/cups/backend/socket", 0x81b49a8, 0xbf836878, -1,
-1, 11)
I [23/Jul/2007:06:02:10 +0000] Started backend /usr/lib/cups/backend/socket
(PID 10113) for job 49.
D [23/Jul/2007:06:02:10 +0000] PID 10113 (/usr/lib/cups/backend/socket) exited
with no errors.
When the printer stops processing jobs, i only have the "Started
backend" line in the error_log, but no "PID xxx (...) exited with ...)
line. ps also shows that the process isn't running any more. From now it
seems that cupsd is eating all cpu power. attaching strace to cupsd
shows that there seems to be a select() loop where the fd of a dead pipe
is part of (i think it's the pipe to the dead socket process).
Maybe some other module 'eaths' the exit / return code from the spawned
socket process? Or just a bug in cups processing the return code?
I found several 'printer stops working' bugs that might be duplicates of
this bug, but i'm not sure so i open a new one...
thanks,
chris
