atcomsystems.ca/forum Forums TDM Business Telephone Systems Samsung Telephones & Systems MCP Reset - Exception or SVM error?

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?
