I would like to add my comments along with Sandeep and Amrinder, as they said this issue looks like memory leak on the Routner. I have gone thruogh the captures which shared by you and i decoded those tracebacks.
------------------ show memory statistics ------------------
Free and lowest memory almost close and Limited avilable memory
Memory allocated or locked by a process and not freed
Another possible cause is a network/traffic event. This will often manifest itself as excessive utilization in multiple pools
A specific pool is more heavily utilized because of certain traffic that is needed in a network environment. This traffic may, for some reason, need to be process-switched and there is no way to avoid this at the current time
Need to check which pool is taking memory leak either I/O or Processor. For our case it is I/O
If I/O, need to check if there is buffer over utilization
Some buffer range should be constantly holding many buffers
Aug 27 19:38:53.649: %SYS-2-MALLOCFAIL: Memory allocation of 780 bytes failed from 0x40327608, alignment 32 Pool: I/O Free: 7504 Cause: Memory fragmentation Alternate Pool: None Free: 0 Cause: No Alternate pool
Please collect the below capture multiple time with different time intervels,
Note: Reserve memory for console access in any case berfore capture these output,

Please share the your issue and symptoms in english and it would you much helpful to investigate the issue further.
