Jabber Clients now getting "Failed to start a new session. Try again" message

[morado2]

HI,

Jabber's been working great for more than 6 years. Now Clients are starting to get the error message "Failed to start a new session. Try again".

Client reset jabber multiple times and continues to error the same error.

Windows 10

Jabber version 11.9.3 build 60004

Started happening last week. Since then there been 2 -3 clients a day getting same error.

I appreciate any suggestions!

Regards,

Tom

When did you last reboot the IM&P cluster or has there been any significant events recently (eg RTMT alarms, subcluster failover or Jabber client version update)? I’m normally not a fan of when-in-doubt-reboot but I vaguely recall a similar symptom from a memory leak years ago.

And what do you use? IM&P or webex?

Getting same issue for all users, all at similar time.

First prompt was the usual "Your session has expired" then click "Renew session" (Error code: CJ:1000:606)

After attempting to renew session get new error: "Failed to start new session. Try again" (Error code: CJ:1000:605)

Anyone have any information on these error codes?

Jabber version: 12.6.1.34405

CUCM/IMP version: 11.5.1(SU6)

CUC version: 11.5.1(SU6)

Edit: Jabber was unable to refresh session with Unity Connection.
