AS5400XM after upgrade from 12.4(4)xc to 12.4(4)xc7 i have the following problem every 5 days: all ethernet interfaces become inaccessible. in logs i see
SYS-2-MALLOCFAIL: Memory allocation of 780 bytes failed from 0x605A7C4C, alignment 32
Pool: I/O Free: 103920 Cause: Memory fragmentation
Alternate Pool: None Free: 0 Cause: No Alternate pool
and show mem command shows
Head Total(b) Used(b) Free(b) Lowest(b) Largest(b)
I/O 20000000 134217216 134114300 102916 102916 716
So the problem is that I/O memory is running low every 5 days. The problem can be solved by reboot, but rebooting as5400xm every 5 days is not good. Does anybody know what can be the cause.
P.S. Before upgrade 12.4(4)xc ios was working just fine and memory requirements for both 12.4(4)xc and 12.4.(4)xc7 are the same.
