Cron question

Hello,

PBX Firmware:6.12.65-30
PBX Service Pack:1.0.0.0
Asterisk: 11.19.0

I’ve had a repeating problem with where my server appears to lose connectivity while using the Broadcast Module. At console, I can start a ping to google and everything starts working again.
This occurs every 18 minutes.

I’ve checked Cron for root and Asterisk and I can’t find anything running at that interval. Is there anything running with this schedule that I should look at?

This is a Esxi VM and I’ve tried upgrading and reinstalling the system, upgrading vnics with no joy.

Thanks,
