This could be due to LSF tracking a VNC process that has not ended. You can issue the following command:
bjobs -l jobid
You should find a list of PPID’s and PID’s. On the system in question, look for the pids and ppid’s using the ‘ps -ef | grep pid’ command.
With VNC, you have to be careful as it likes to daemonize processes. Which LSF will continue to track. The way you avoid this is by preventing VNC from damonizing the commands by enabling:
LSB_RESOURCE_ENFORCE=“cpu gpu memory”
In your lsf.conf, then restart everything. However, after that VNC may not be happy.
If on the other hand either ‘bjobs -l’ shows no pids or ppids, or those pids and ppids don’t exist, you may have stumbled on an LSF bug. In that case, restart the sbatch on the host, then open a ticket with support or apply the latest LSF service pack.
