428746 - crash in ocsp_RemoveCacheItemFromLinkedList during shutdown

Status: RESOLVED WORKSFORME

(NSS :: Libraries, defect, P1)

Description

[Kai Engert [:KaiE:]]

We recently worked on a fix for Firefox.
There was a hang on exit, a deadlock.

As part of that bug, we used a test case that involved a lot of parallel SSL connections, involving OCSP checks, and exiting the application while several of these are still active.

Now, the deadlock appears to be fixed, and we continued to try what happens when we run that test.

Occassionally, I get a crash.

I got this assertion:
Assertion failure: item->moreRecent->lessRecent == item, at ocsp.c:454

And I'll attach the stack.

I wonder if this bug is a side effect of the cause of bug 433594, which is
now fixed.

Kai, can you determine if this bug persists, now that bug 433594 is fixed?

Having heard nothing more about this bug in 9 months, I'm assuming it's 
no longer a bug.  If it is still a bug, we need new evidence.
