Hi ,

Today we got an error in JFD log:

2020 Jun 07 16:16:28 2496 8268 4 JFLSFEventsFile::_openNextFile(): Cannot open any events file. Exited.: error 53: The network path was not found.
2020 Jun 07 16:16:44 2496 8272 3 JFJobExecutionAgent::_executeCommand: (neovia\lsfadmin) Exited with -1.

Why it is happen ? where we can find the missing file? once we stopped and restarted the following services . it solved .

Its probably an intermittent network issue. Looks like you have some network file sharing enabled wherein LSF couldn't find the network path. If this is regular, you should do some checks on what is causing this, probably network?

Hi,

Thanks anand. Just can you clarify where I can find the path for JFLSFEventsFile? why I should stop and restart the services if it is intermittent network issue, it would have started automatically once network solved right?

JFLSFEventsFile is usually read from the events file lsb.events usually located under LSF_TOP/work/cluster/logdir/

You can't change the path just like that. Its part of the while LSF configuration files. I don't think it's a good idea. Are you facing this issue again and again? If not, I believe you can continue using this way. If not, check with network team on what is causing this behavior.

Hi,
Thanks. i installed the flow manger in server .we are using VDI for client system . I just found the events path in VDI . so we can not change the path of it ?

This path is as part of installation of flow manager for client or JFD/LSF on server. I don't advise it to change for a single file, unless you want to reinstall everything.
