Thread: openldap segfaults randomly

hi,
i've server openldap setted up, , has been working last 2 month without problem.

2 days ago started segfault randomly, every 60 90 min aprox.
taking @ logs cannot see gives me hint happening.
i've had set cron job start slapd every 30 min, keep working.
don't think it's related hardware failure, since it's inside vm server , other servers didn't had trouble.

error is:
sep 29 18:03:49 earth kernel: [ 3460.052677] slapd[2522]: segfault @ 0 ip 00007f20f0285ee6 sp 00007f20eab933d8 error 4 in libc-2.9.so[7f20f0205000+168000]
