v10 RTM / VAL 4.0 - Segmentation fault on CentOS 7

Post by premeau »

After updating to VAL 4.0 from the v10 RTM bundle, my CentOS 7 system throws a segfault when attempting a backup.

It appears to be after the snapshot process, but before the backup starts.

Case #03994568

Code: Select all

Hi @premeau,

Which glibc version do you have installed on the server?

Thanks

To close out this thread:

Apparently the fault was caused by the fact that this system had alias interfaces eth0:1, eth0:2.

The issue is no longer present in the GA (4.0.0.1961) version of VAL.
