This error was reported by your PLIM ASIC (PLA0). We have 2 of them on every PLIM. This is a log level 5 - notification.
That said, its better you proceed with a TAC case as you might want this to be looked just to be safe.
If you like to track this down I would run the following commnad:
show asic-errors plim asic 0 all location 0/x/CPU0 - X stands for the slot #.
The same info can found in "dir harddisk:/ASIC-ERROR. We keep these records in case the LC had been reset by the system in case we had expereinced an event where we could not recover.
This is all valid for a single/random occurance, if you keep get this message in your syslog and the output of the above command shows a pattern or a trend please go ahead and open SR.
When you do, please capture the following:
show ver br
show inst ac su
ad show platfrom
admin show diag
show asic-errors plim asic 0 all location 0/x/CPU0
show asic-errors plim asic trace all location 0/x/CPU0
show controllers plim asic summary location 0/0/CPU0 <= That maps your PLA to interfaces and/or SIP/SPA HW if exists. Since this is Taiko (CRS-3 AKA 140 Fabric/Line Cards) and I see XGE, I would guess your PLIM is one of these:
