Symptom

SSH sessions on XR/server side are stuck in OPEN state resulting in hitting the configured ssh sessions limit there by causing ssh to fail. TCP connection for corresponding ssh sessions are in ESTABLISHED state. On the client side, ssh session is getting closed/terminated.

Conditions

Random ssh sessions initiated from client remain stuck in OPEN state on the XR/server. Corresponding TCP sessions will remain in ESTABLISHED State on both client and server because three way handshake was already completed.

Workaround

clear stuck/stale sessions manually #clear ssh
