namcd crash and coredump

[aanthonisse]

Hi,

On a OES2 (non SP1) server of a customer the namcd process crashes and cores frequently, somtimes more then once on a day.

/var/log/messages shows
/usr/sbin/namcd[5451]: *** glibc detected *** /usr/sbin/namcd: double free or corruption (fasttop): 0x00002aaaaad0e9d0 ***

There is also a corefile created. Info from corefile: core.5451: ELF 64-bit LSB core file AMD x86-64, version 1 (SYSV), SVR4-style, from 'namcd'

namconfig get information:

This problem exists from the first day of installation. A workaround has been created with a cronscript that monitors existance of namcd and restarts namcd if it is not running, but I like it better when the problem is solved.

Where to look for a solution (besides upgrading to OES2SP1)?
