Backup fails during dump

[Hannes_S.]

After successful creation of a full backup, pmm-ras hangs forever (100% CPU) while trying to export the dump to FTP. I have two identical Plesk 12.0.18 installations and this happens only on one of them.

I see the following in /opt/psa/PMM/sessions/*/.stderr:

Use of uninitialized value in numeric eq (==) at /opt/psa/admin/bin/plesk_agent_manager
line 827.

pmm-ras (plesk-migration-manager repository-access-service) is responsible for organization of backup repository and all transactions with repository.
For debugging you should change FORCE_DEBUG_LOG from 0 to 1in /usr/local/psa/admin/share/pmmcli/pmmcli-rc
Then repeat backup procedure check log like /var/log/plesk/PMM/backup-2015-02-02-xxxxxxxx/backup.log for any pmm-ras mentions.

I did that. pmm-ras is mentioned three times:

1. pmm-ras started : /opt/psa/admin/bin/pmm-ras --get-dump-info [...]
2. pmm-ras finished. Exit code: 0
3. pmm-ras started : /opt/psa/admin/bin/pmm-ras --export-dump-as-file

Now the pmm-ras process hangs again for more than 3 hours and using nearly half of my RAM (3,8 GB) and 100% CPU constantly.
I cannot see any progress in one of the log files, neither under /var/log/plesk/PMM/ nor under /opt/psa/PMM/sessions/[...].
The last entry in /var/log/plesk/PMM/backup-2015-02-02-11-03-08-627/backup.log is "No output on STDERR were performed by the utility" - the lines before that show a file listing.

Looks like there is something wrong with uploading dump on FTP server. Have you checked FTP logs? Contact Support Team if you find nothing more.
