Pbs_mom using ftp in keepalive on one server

I’m new to PBS so bear with me. I have a single Linux client that seems to be fine but it’s oddly using ‘ftp’ in the keepalive. FTP is not a service running on the system but it appears in a keepalive. Excuse the formatting. So, this is currently being flagged as a vulnerability and it’s not the same port as the others. Let’s say the others are using port 555 as an example. I can’t for the life of me find any evidence of a port being set so maybe someone here can help point me in the right direction.

netstat -ano | egrep ':1902'
tcp        0      0 10.0.10.1:21       10.0.10.100:1902    ESTABLISHED keepalive (3.76/0/0)


lsof -i :1902
COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
pbs_mom 1234 bob   13u  IPv4  21306      0t0  TCP the-client:ftp->the-server:1902 (ESTABLISHED)

Could you please share the version of openpbs you are running ?
Also, share the contents of your /etc/pbs.conf

PBS Version:
qstat --version

Contents of pbs.conf;
cat /etc/pbs.conf

Note: openPBS does not run or require a ftp server or service.
