| |
Hello,
I got this with 3.0 perf, but the running kernel is a old one:
[root@hp-dl580g7-01 perf]# ./perf kmem record sleep 1 [ perf record: Woken up 0 times to write data ] [ perf record: Captured and wrote 21.789 MB perf.data (~951977 samples) ] Processed 0 events and LOST 76148!
Check IO/CPU overload!
[root@hp-dl580g7-01 perf]# ./perf kmem stat Processed 0 events and LOST 76148!
Check IO/CPU overload!
SUMMARY ======= Total bytes requested: 5725028 Total bytes allocated: 6291512 Total bytes wasted on internal fragmentation: 566484 Internal fragmentation: 9.003941% Cross CPU allocations: 28/84295
Is this a bug?
Thanks.
