Backup issue

[coper]

Hello, I need a little help with this backup issue please.

When backup runs the three values of server load average goes too hi (over 150), the domains don't work and I can't connect to the server by ssh until backup ends.

The problem it isn't in this part of the backup because I moved the schedule to 5:05 am and this happens at midnight

# Backup
5 5 * * * root /var/www/ispcp/engine/backup/ispcp-backup-all yes &>/var/log/ispcp/ispcp-backup-all-mngr.log
5 5 * * * root /var/www/ispcp/engine/backup/ispcp-backup-ispcp noreport &>/var/log/ispcp/ispcp-backup-ispcp-mngr.log

I attached to this post my ispcp backup script inside /etc/ispcp/cron.d/backup/

After this problem I can see this lines inside the ispcp-backup-all-mngr.log file:

Code:

mysqldump: Got error: 2013: Lost connection to MySQL server during query when using LOCK TABLES
Can't use string ("") as an ARRAY ref while "strict refs" in use at /var/www/ispcp/engine/backup/ispcp-backup-all line 324.

I appreciate any help to solve this problem.

Thanks in advance,

Regards.
