Bug #3609
Updated by Joao Eduardo Luis over 11 years ago
Left a couple of monitors running overnight with heap profiling active.
Don't have the logs, as I wasn't expecting it to work (yet again) and had simply forgotten to kill the cluster.
This however produced some neat heap profiles that were finally usable -- my guess is that disabling -O2 and letting the monitors run free during the night helped a lot.
Now, the good stuff.
<pre>
mon.b
Total: 337.4 MB
337.4 100.0% 100.0% 337.4 100.0% ceph::buffer::create_page_aligned
[snip]
mon.c
Total: mon.c
*Total: 2269.0 MB MB*
2269.0 100.0% 100.0% 2269.0 100.0% ceph::buffer::create_page_aligned
</pre>
Note that in this case mon.b is the leader. At least it was supposed to be, unless something went awfully wrong and quorum was broken. I have no idea if that indeed happened, as I just killed them when I logged back into the server and noticed they were up.
By the way, this is running v0.55 (690f8175606edf37a3177c27a3949c78fd37099f).
Full heap profile attached.
