Hi
We have a 2921 ISR G2 Router with 6 E1 Cards and Total number of 56 Dial-Peers active on it and 512 MB of Ram.
The IOS Version is 15.2(4)M4 and there’s a PVDM3-256 installed on it. Some days ago the router reloaded accidentally at the end of the work hours. After further lookups we came up with these Information:
Max Memory Usage at the time of Incident: 230MB
Max Total Concurrent Calls active on the Router at the time of reload: 14 Calls
The following is the the last events occurred in the time of crash:
