63514 - PR_Sleep stucks sometimes on AIX

Status: RESOLVED INVALID

(NSPR :: NSPR, defect, P1)

Description

[ARNOU]

Hi,

I use NSPR on AIX 4.3.3. I have some threads doing operations, and I need to
sleep some of these threads under certain circumstances. 
It works correctly upto it stucks randomly. 
Here is the stack:

_spin_lock_global_common(??, ??, ??) at 0xd00072b0
malloc.__heap_lock(??, ??) at 0xd01645c8
malloc.free(??) at 0xd0165e48
pthread_cond_destroy(??) at 0xd000f600
unnamed block $b1989, line 316 in "ptsynch.c"
ptsynch.PR_DestroyCondVar(0x3035f678), line 316 in "ptsynch.c"
unnamed block $b2043, line 754 in "ptthread.c"
ptthread.PR_Sleep(0xbec), line 754 in "ptthread.c"

Do you have any idea on this point ?

Regards,
Jerome ARNOU

We have not received reports of this problem before.
The stack trace shows that the thread is waiting for
the heap lock. It looks like some other thread is
holding the heap lock and not releasing it.

Are you using NSPR 3.1, as indicated by the Version
in this bug report?

We just discovered, the AIX machine on which we reported this pb was not
correctly patched.  The patch referenced with the No 5765-C34 corrects a
possible pb of threads hanging ... and the stuck in PR_Sleep is also corrected
