[Bug 512220] Re: cupsd crash "Closing on unknown HTTP state 0"


I disabled internal logging with "MaxLogSize 0" but we have the issue
again. Also I can confirm it really depends on what you are printing,
since we have 10 identically configured servers and on some of them it's
not visibel at all, on others it's happen almost daily.

  cupsd crash "Closing on unknown HTTP state 0"

Status in “cups” package in Ubuntu:

Bug description:
  Binary package hint: cups

  I often get trouble with cupsd crashing and Apport saying the

  The problem cannot be reported:
  The program crashed on an assertion failure, but the message could not be retrieved. 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] cupsdCloseClient: 11
  D [25/Jan/2010:08:57:16 +0100] cupsdSetBusyState: Not busy
  D [25/Jan/2010:08:57:16 +0100] cupsdWriteClient: 1354538648 Closing on unknown HTTP state 0
  D [25/Jan/2010:08:57:16 +0100] cupsdCloseClient: 1354538648

  How to reproduce:
  0) Make sure you have session restore activated. 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.
