reboots caused by SABNZBd?

Last night around 3 am, my system rebooted. I believe it had issues at least 4 times before that. (uptime monitoring timed out) I did see that downloads occurred around the same time.

/var/log/messages showed nothing except the booting up. The only thing that changed was upgrading to 9.3.1 the day before (if i recall correctly)

So where can I look?

Today, while downloads were occurring, the system rebooted repeatedly. Everything was stable, not sure what changed.

Edit again: Could be just network card utilization, nothing related to SAB.

Typically, reboots at that time of day are due to system load on under-powered systems from running the periodic security scripts. What's the RAM and CPU on the system? Any other tasks running at that time (replication or a cron job)?

It is an i7 with 8 GB of RAM. I don't have any scripts (yet)
