[Networker] glibc on RHEL4 x86-64 and nsrexecd core dump
2008-02-11 17:30:01
I've looked through the archives and found a couple of references,
mostly to the double free message below. Suggestions have included
disabling nsrauth for a client and modifying environment variable
MALLOC_CHECK_ to prevent nsrexecd from being killed immediately (both
from 2 years ago). I'm having an issue where I am receiving one of
these messages at different nsrexecd core dumps.
*** glibc detected *** double free or corruption (fasttop):
0x0000002a987ffc30 ***
*** glibc detected *** corrupted double-linked list: 0x00000037e6c316b8
***
I am running v7.3.3 Networker - 64-bit on RHEL4 ES Update 6 x86_64. If
I restart Networker and the group in question everything is fine for a
while which can be a day, a few days, a week, ... and then it happens
again. I have a separate smaller system running the 32-bit OS and
Networker and it does not have this issue.
Has anyone else worked this issue to a happy conclusion? Is going to
the 32-bit Networker a viable option? I don't have the luxury of a test
system, so, any solution needs to have good track record.
