Crash during backup

[spearox]

Hi!

I got a problem. VM crashed during the backup in snapshot mode. I get this error on syslog:
Feb 14 01:57:50 XXXX kernel: kvm[7999]: segfault at 2040 ip 0000561528a793d6 sp 00007ffc37139ea0 error 4 in qemu-system-x86_64[5615284a0000+7bd000]

Why is that?

> pveversion -v

We had this issue last night also. In the journal-logging only this message appeared:

Mar 18 23:02:52 proxmox-host kernel: kvm[6558]: segfault at 2040 ip 000055f5bdb16b66 sp 00007ffe3ad17300 error 4 in qemu-system-x86_64[55f5bd53e000+7bc000]

This was also when we take a scheduled backup with snapshot mode of the VM. This is our output of pveversion -v
