3.4.3 undesired midnight shutdown

[twistmachine]

Hi folks,

I come to you today for a little problem with the last nagios version 3.4.3

As i was aware of the problem with the downtime system with the 3.4.1 version, i needed to upgrade to the latest version for fixing this issue.
So after this, no more problem with the downtime.

But it seems that all night, exactly at midnight nagios hang and is shutdowned (really strange). you can see the error message below :

[1355353200] HOST DOWNTIME ALERT: xxxx;STARTED;No comment
[1355353200] HOST DOWNTIME ALERT: xxxx;STARTED;No comment
[1355353200] HOST DOWNTIME ALERT:xxxxx;STARTED;No comment

[1355353200] SERVICE DOWNTIME ALERT: xxxx;CPU utilization;STARTED;No comment
[1355353200] Caught SIGSEGV, shutting down...

is someone has encounter the same issue ?
or if the community has an idea about this, im listening.

Thanks for your help

Has this only been happening since the upgrade, or was this an issue with previous versions? Is your system configured to create core dumps upon crashing? It may be helpful to look at the core file if so.
