Can anyone tell me what seem to be the problem? My customer has an OS7400 PBX. Recently I see MCP Reset - Exception error, and SVM NTWK Error in alarm history. It seem like the PBX rebooted randomly for the past whole week. Here is what in the alarm history.

What are the possible causes for the reboot? IP conflict on the SVMI-20i, or database issue on the MP card? Please advise , thank you!

**I actually found some of our other customers also have similar issue on OS7100, and OS7200. Does anyone else have this issue with their customers?

Did some digging around... and found... there was a possibility that some external source was attempting to flood the phone system. Which caused the processor card out of control, and rebooted the PBX.

Yes we've started seeing this recently, restricting the port forwarding on the firewall to known IPs works.
