if BackupPC files from dir /var/lib/BackupPC is moved to NFS mount, web interface not working. I see an only home page, but when I want to go to host config or to summary webpage timeouts (504 Gateway Timeout).
In BackupPC logs isn't anything relevant. In httpd error log are these lines:
[Wed Jun 07 14:39:04.655260 2017] [cgi:warn] [pid 1078] [client 83.208.46.101:53404] AH01220: Timeout waiting for output from CGI script /usr/share/BackupPC/sbin/BackupPC_Admin, referer: http://10.0.0.15:8081/backuppc?action=summary

If I switched configuration back (/etc/BackupPC/config.pl, variable $Conf{TopDir}), all works fine.
I use CentOS Linux 7 x64 and BackupPC-3.3.1-5.el7.x86_64
