Re: [ceph-users] Potential OSD deadlock?

We set the logging on an OSD that had problems pretty frequently, but cleared up in less than 30 seconds. The logs are at http://162.144.87.113/files/ceph-osd.112.log.xz and are uncompressed at 8.6GB. Some of the messages we were seeing in ceph -w are: 2015-09-20 20:55:44.029041 osd.112 [WRN] 10 s
