Repeated fabricq log messages occurring continuously, at a rate of up to ~15 messages per hour:

RP/0/RP0/CPU0:Dec 23 09:04:45.305 : fabricq_mgr[228]: %FABRIC-FABRICQ-3-PCL_PKT : Minor error in PCL of fabricq asic 0. PCL UC Partial Packet: CAOPCI: Unknown context

Symptom:Repeated fabricq log messages occurring continuously, at a rate of up to ~15 messages per hour:

RP/0/RP0/CPU0:Dec 23 09:04:45.305 : fabricq_mgr[228]: %FABRIC-FABRICQ-3-PCL_PKT : Minor error in PCL of fabricq asic 0. PCL UC Partial Packet: CAOPCI: Unknown context
RP/0/RP0/CPU0:Dec 23 09:06:45.934 : fabricq_mgr[228]: %FABRIC-FABRICQ-3-PCL_PKT : Minor error in PCL of fabricq asic 0. PCL UC Partial Packet: CAOPCI: Unknown context

Conditions:Seen in steady state on CRS multichassis systems with Satori SpongeB (4 Channel FCRAM) cards.
Logs indicating PCL drops are seen, haven't seen any impact on the control & forwarding planes. At times, MCWEDGE condition is reported on the Satori-RP fabricQ ASIC and this results in a SW triggered reset of ASIC to recover from the state. 

Not seen on Satori 8 channel FCRAM cards. Occurrence of the issue on Single Chassis/Back-to-Back systems are rare, but cannot be ruled out.
