FAQ
Greetings,

I am seeing this a lot in trace files in the bdump directory. This is a
two node RAC cluster running 1ogR1 Standard Edition on REHL3. I can't
find anything with google.

    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.
