After a recent upgrade to Plesk 9.5 for Linux, I started receiving the following error messages on a daily basis :

/bin/sh: line 1: 2462 Segmentation fault /usr/local/psa/admin/sbin/backupmng> /dev/null 2>&1;

It seems that, when Plesk performs a backup using backupmng utility, there is an error, and you may find errors simliar to below in /var/log/messages log file :

Mar 24 01:33:02 : backupmng[30573]: segfault at 0000000000000010 rip 00000039b6a4a855 rsp 00007fff4fa91710 error 4

Resolution – provided by Plesk

Fixed backupmng utility for CentOS 5 and Debian 5 in attached file.

For fix installation replace %plesk_dir%/admin/sbin/backupmng file by file from attach and correct owner and permissions, it should be root:root, 750.

A simple command to ensure permissions are correct; chown and chmod:

chown root:root /usr/local/psa/admin/sbin/backupmng
chmod 750 /usr/local/psa/admin/sbin/backupmng

Note: %plesk_dir% is environment variable which points to Plesk installation folder. By default it is /usr/local/psa/
