So an update for anyone else having this issue. It looks like radosgw
either has a memory leak or it spools the whole object into ram or
something.
root@kh11-9:/etc/apt/sources.list.d# free -m
total used free shared buffers cached
Mem: 64397 63775 621 0 3 46
-/+ buffers/cache: 63725 671
Swap: 65499 17630 47869
root@kh11-9:/etc/apt/sources.list.d# ps faux | grep -iE "USE[R]|radosg[w]"
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 269910 134 95.2 90622120 62819128 ? Ssl 12:31 79:37
/usr/bin/radosgw --cluster=ceph --id rgw.kh11-9 -f
The odd things are 1.) the disk is fine. 2.) the rest of the server
seems very responsive. I can ssh into the server without any problems,
curl out, wget, etc but radosgw is stuck in the mud
This is after 150-300 wget requests to public objects, 2 radosgws freeze
like this. The cluster is health okay as well::
root@kh11-9:~# grep -iE "health" ceph_report.json
"health": {
"health": {
"health_services": [
"health": "HEALTH_OK"
"health": "HEALTH_OK"
"health": "HEALTH_OK"
"health": "HEALTH_OK"
"health": "HEALTH_OK"
"health": "HEALTH_OK"
"overall_status": "HEALTH_OK",
Has anyone seen this behavior before?
