Segmentation fault

Hi *, XSIBackup-DC was running fine for about three months, then it started to produce "Segmentation fault". unfortunately, this was not recognized for quite a while :-/

output:

Re: Segmentation fault

There is a bug we just fixed by which if some VM in the list of VMs to backup does not exist any more the job SEGFAULTS. Check that you aren't trying to backup some VM that you removed or renamed.

Also, by the way you describe your issue, you could have filled some temp folder. Check that you have space in the root FS and /tmp by issuing:

df -h
vdf -h

We recommend that you update to the latest version, yours is rather outdated.

Re: Segmentation fault

the VM mentioned in the job [i]"VMs(restore)"[/i] exists, for sure:

It also seems, there is enough space:

latest version i've to check, as [i]Your support finished on 2023-07-23T00:00:00+00:00)[/i]. unfortunately the backup was working for about 2 months only (2022-07-16…2022-09-30), then it created the backup-dirs (it looked ok) but without content (that is why it was not recognized earlier).

i've already deleted all empty dirs in the meantime, except for tests i did recently (since 2023-11-28)

Re: Segmentation fault

version 1.7.1.3 works as expected. same configuration, no segfaults.

just for reference, the esxi host is a fully patched 6.7u3: ESXi-6.7.0-20221004001-standard aka build#20497097 aka ESXi 6.7 P08
