427267 - mochitest sometimes fails with "An event was posted to a thread that will never run it"

Status: RESOLVED INCOMPLETE

(Core :: General, defect)

Description

[Andrew Schultz]

Sometimes running mochitests, I hit:

WARNING: An event was posted to a thread that will never run it (rejected): file /home/andrew/tbox/SeaMonkey-mochi/Linux_2.6.22.14-72.fc6_Depend/mozilla/xpcom/threads/nsThread.cpp, line 359
WARNING: leaking reference to nsTimerImpl: file /home/andrew/tbox/SeaMonkey-mochi/Linux_2.6.22.14-72.fc6_Depend/mozilla/xpcom/threads/nsTimerImpl.cpp, line 464

... and then the tests stop running.  I have to quit SeaMonkey or wait for runtests to timeout.  I suspect this happens occasionally on the FF tboxes but they don't build debug, so it just shows up as a mystery hang.  This probably also happens outside of mochitest, but the app remains usable, so nobody notices.

If you can get a decent test case, that consistently reproduces the hang, then great.  'Til then -'ing.

the warning is from bug 404870
