Hello, everybody! I'm using kernel 3.10.0-2-pve and saw logs segmentation today one of the workers pveproxy.
Code:
[534952.224767] pveproxy worker[18844]: segfault at 4 ip 00007f0d3e465493 sp 00007ffff7885378 error 4 in libqb.so.0.11.1[7f0d3e44e000+1f000]
I also meet periodically such records:

Today I saw this picture again with errors pveproxy, Does anyone have any information on what is this?
Code:
[1010528.295968] pveproxy worker[20923]: segfault at 4 ip 00007f0d3e465493 sp 00007ffff7885378 error 4 in libqb.so.0.11.1[7f0d3e44e000+1f000] [1027113.910667] pveproxy worker[26488]: segfault at 4 ip 00007f0d3e465493 sp 00007ffff7885378 error 4 in libqb.so.0.11.1[7f0d3e44e000+1f000]
 
Check your RAM.
You mean checked using Memtest86+ ? What can be wrong with the memory in the server fairly new strip of RAM as well as other hardware ? Сервер: DELL POWEREDGE C6100 XS23-TY3 4 x NODES 8 x 2.8GHz X5560 96GB

Yes with memtest86++

Excluding mechanical hard drives, I have had more failures from new hardware than I have from old hardware.
Just a couple months ago I had to RMA a new $2000 Intel CPU because it had a flaky memory controller causing random bit flips
I have even had ECC RAM that was so bad the errors were uncorrectable.

If other users were having the same issue I would suggest it is a bug.
But since it is only you the most logical conclusion is you have a problem with your hardware and the most common hardware problem to cause segfault is bad RAM.
