What is the exact kernel version ?

Ubuntu has a new tcmalloc incorporated from 3.16.0.50 kernel onwards. If you are using older kernel than this better to upgrade kernel or try building latest tcmalloc and try to see if this is happening there.

Ceph is not packaging tcmalloc it is using the tcmalloc available with distro.

 

Thanks & Regards

Hi,

 

Been getting some segfaults in our newest ceph cluster running ceph 9.2.1-1 on Debian 8.3

segfault at 0 ip 00007f27e85120f7 sp 00007f27cff9e860 error 4 in libtcmalloc.so.4.2.2

 

I saw there’s already a bug up there on the tracker: http://tracker.ceph.com/issues/15628

Don’t know how many other are affected by it. We stop and start the osd to bring it up again but it’s quite annoying.

 

I’m guessing this affects Jewel as well?

 

Kind Regards,

 

David Majchrzak
