Unable to restart LFD from webmin

[gmariani405]

I'm running CentOS 7 with csf v14.08. If i log into webmin and restart CSF it works fine. If i go to restart LFD, it shows a blank response and says done. But on SSH, it says that the LFD restart is pending, and will stay that way for 90s until it times out and the service is killed. Which after that, the webmin interface dies. Here is the service status log before, during and after I try to restart from webmin.

For what it's worth, if i run csftest.pl this is what i get:

Code: Select all

[root@filter modules-load.d]# perl /usr/local/csf/bin/csftest.pl

RESULT: csf should function on this server

We are unable to recreate a problem. Ran on a fresh CentOS v7.9 install with webmin v1.962.
