Daily periodic cronjob generates core dump

[C. L. Martinez]

Hi all,

 I have a FreeBSD 9.1 host (fully patched) with ZFS. Every day I am
receiving in security output this message:

fbsd.domain.local kernel log messages:

+++ /tmp/security.AT1oDecp   2013-06-14 03:02:10.000000000 +0000

+pid 75930 (try), uid 0: exited on signal 10 (core dumped) pid 76241

+(try), uid 0: exited on signal 10 (core dumped)

 How can I detect where is the problem??

 Thanks.
