I’ve been getting this strange error on my M7i logical-system lab router recently.
I’m currently running 12.3R3.4:
[email protected]> show version Hostname: M7i Model: m7i JUNOS Base OS boot [12.3R3.4]
When trying to commit now and then I see the following error:
[email protected]# commit and-quit error: Check-out pass for Logical system multiplexer process (/usr/sbin/lrmuxd) dumped core (0x86) error: configuration check-out failed
Nothing is wrong with the config itself. I’ve found a quick way to get rid of it is to add a new interface to a logical system and then remove it straight away. The config then commits:
 [email protected]# set logical-systems R4 interfaces fe-0/2/8.0  [email protected]# delete logical-systems R4 interfaces fe-0/2/8.0  [email protected]# commit and-quit commit complete Exiting configuration mode
