Does it still happen after restarting radosgw?

#4 Updated by Matt Benjamin almost 2 years ago

surprising to see this in v10.2.10, n.b., new async gc code is upstreamed to master and planned for backport

yes radosgw will coredump every a hours. the period just the gc thread scheduled timestamps.

I delted all omapkeys of the gc.* objects in the gc pool. it will be ok,not cordump again.

from backtrace ,it seems like to assign string with the invalid string external string ptr.

did have method configure systemd cordump with ceph?

I have test send kill -11 my a.out started systemd . but same way is invalid to radosgw and osd.

below is new setted in systemd configure files
LimitCORE=infinity

I have successful got the coredump configure with systemd.
If I get the string external information in the future,will paste it to here.

@yehuda points out that deleting the underlying pool during GC is difficult to support
