kewr prefix is for Kernel Workload Repository as far as I understand. The trace file is most probably from m000 process (MMON_SLAVE). What are GRFR? maybe something like Global Request to Flash Remotely.

MMON collects information all the time including frequent samplings of session waits (ASH data). It has cyclical memory buffer. This buffer is flashed to disk from time to time including times it gets full.

Perhaps, there is also global trigger to flush buffers and the request has timeout. Maybe during the AWR snapshot it requests all instances to flush its in-memory AWR data? Can't say for sure but it does make sense. Can you check timestamp of your AWR snapshots and see it it matches the errors? Of course, only if you are licensed otherwise you can't select from those views without license violation even if AWR causes you troubles.

So it seems timeout occurred waiting for that. Why? Another node busy or whatever else the reason for not getting it done on time. Do you experience any issues due to that? Don't know if it affects anything besides AWR data. I would open an SR if that bothers you.
