  • Applies to:
  • Plesk 10.x for Linux

Symptoms

1. It is not possible to log in to Parallels Plesk Panel UI. Once login/password is entered and the Log In button is pushed, the browser gets stuck loading information from the Parallels Plesk Panel server.

2. Parallels Plesk Panel is installed within a PVC container.

3. Lots of filwrpr processes are running on the server:

# ps -aux | grep filwrpr
root 2038 0.0 0.0 49260 2476 ? S Jul28 0:00 /usr/local/psa/admin/bin/filwrpr 11
root 3143 0.0 0.0 49260 2484 ? S Jul28 0:00 /usr/local/psa/admin/bin/filwrpr 12
root 3248 0.0 0.0 49260 2480 ? S Jul28 0:00 /usr/local/psa/admin/bin/filwrpr 28
root 8121 0.0 0.0 49260 2480 ? S Jul28 0:00 /usr/local/psa/admin/bin/filwrpr 60

4. The file /etc/linkmgr.conf on the PVC node where the Parallels Plesk Panel container is running contains two lines (excluding comments) as below:


# cat /etc/vzlinkmgr.conf
# This is a comment
0=/usr/sbin/vzaiproxy
1=/usr/sbin/concerto

Resolution

On the PVC node where the Parallels Plesk Panel container is running, edit file /etc/vzlinkmgr.conf and comment out the line with vzaiproxy:

# cat /etc/vzlinkmgr.conf
# This is a comment
#0=/usr/sbin/vzaiproxy
Thank you for understanding and cooperation.
NOTEVZAIproxy is not supported by Parallels Plesk Panel since version 10.0.

Restart the vzlinkmgr service to apply changes:

# /etc/init.d/vzlinkmgr restart

Alternatively, replace the /usr/local/psa/admin/bin/filwrpr file with one taken from the Parallels Plesk Panel version 9.5.4 distribution for the same OS.
