Quantum vmPRO internal filesystem /var/log is low on space: 100% used (0 MB free).
Backups are still working and log reports are still running. Did the vmPro image reach its limit on the log file and is now dropping off the oldest logs?
This won't clear itself and because there is no space left in /var/log I assume logging is impacted but I am not 100 on this. What you can do is copy the log files (ls_bitmap_fs.x) to another location, compress them and then move them back.
