Description (partial)


cHDLC MA process crashes on resync with L2VPN Mgr. When cHDLC MA restarts, everything will recover back to the correct state, and the crash will not occur again.


This issue can only occur in a very rare corner case, where the l2transport configuration is removed from an interface while cHDLC's connection to L2VPN Mgr is down. If there is no l2transport configuration, the condition cannot occur.

The issue exists in the following releases:
- R3.6
- R3.7
- R3.8
