Memory leak when polling cswSwitchInfoTable via SNMP
Symptom: Memory leak leading to switch crash
Conditions: This has been observed on stacks of Cisco3750 running Cisco IOS software 12.2(25)SEE1 when polling the SNMP object cswSwitchInfoTable from the CISCO-STACKWISE-MIB

My recommendation would be that you consider a migration of code on the switch stacks that experienced the problem to a version that contains the fix for the above defect.
The other image you are running in production, 122-46SE, is not affected by CSCsg18189.
