Hi,
Sorry for the delayed reply.
Cause may be:
The message is a warning that FLARE is having trouble scheduling tasks, which could be caused by
a thread running incorrectly at an elevated priority level. It indicates that the Storage Processor (SP)
is getting close to invoking the CPU1_Watchdog panic. For arrays under heavy load FLARE can
control the CPU, which would result in the warning being generated. In some rare circumstances,
the message is being generated by FLARE copying a large amount of cache over to the other SP.
check storage performance or engage EMC performance specialist.
