MBT Event on CPU and Memory reset Automatically.

Dear Experts,

We are facing a problem in one of our H-systems.

Suddenly standby cpu went to stop mode.

We have checked the diagnosis and its as below.

First MBT Event Came.

Second Master CPU went to SOLO mode.

Third standby cpu went to error check mode.

Than memory reset in Standby cpu.

Can anyone please tell what is MBT Event.

I am attaching the diagnosis buffer for reference.

Time of Event:04:09

Dear Experts,

I am having the same problem with PCS7 8.2 and 410-5H system. Because this is the only place I find something about MBT event I will post it here...

From diagnostic buffer first we have MBT event, after that switchover of the master and standby CPU, then from redundant to solo mode... Then BZS Event whatever that is!

After few minutes link-up, memory reset of failed CPU and again redundant mode.

Few rows from diagnostic buffer:
