Description (partial)

Symptom:

This bug is a replacement solution for the bug CSCsx72877.
Sometimes in linecard, ISR and higher priority tasks are busy so that IPC keepalive messages could not get disposed in time, which could lead to IPC connection down and linecard crash.

Conditions:

In large testbed, for example, over 3000 modems in one linecard, during startup, we may see the linecard crash due to IPC timeout.
