On a MX480 VC, with 2 members, and 2 REs each member, while committing the configuration, we might get the below message:

--------------------------------

lab-RE0# commit synchronize

Broadcast Message from root@IPMPLS-MX480-ASN-ME0-RE1

(no tty) at 13:10 MUT...

Force commit synchronized requested on another RE.

All configuration sessions on this RE will be terminated

----------------

There are 2 workarounds for the mentioned issue:

• One workaround is to perform a "commit full synchronize" from master of VC.
• Other workaround is to:

From shell mode, restart the irsd process from backup RE using the pid-value.

root@S1> show system process extensive | match irsd

<pid-value> root 1 96 0 5440K 3288K select 0:02 0.00% irsd

root@S1> start shell

root@S1% kill -9 <pid-value>

If step 1 does not clear the alarm, I suggest to proceed with step 2 in a MW.
