Unmarshal errors

I'm seeing alot of errors that get returned to me and the job never got kicked off.
Is this some type of network or communication error??

See below...

is: java.io.EOFException

It sounds like the job is dying on the remote agent side before it can return its status to the scheduler, thus EOFException (end-of-file on communication channel). I think I've seen such errors before. Which version of the scheduler are you running? Is the agent version the same?

I think I may know part of the issue.
The log file on the agent was 6.4 GB.

Also I think there may have been some issues with the agent process itself.
So, I restarted the agent, which creates a new log file.

We will see how it goes, feel free to comment on the error and if you think that may have been part of the issue.

Thanks.

Hi, since I have restarted the agent and cleaned up the log files all seems well so far.
All agents and master scheduler are on the same version which is 4.4.322 Multi-Platform.

I suggest scheduling a weekly or monthly job to archive (zip with a time suffix) and delete agent log file. Typically this is done using mv command to move active log file to log archive directory then gzip to compress it and rename with a time suffix and lastly using rm command to the delete log file from archive directory and leave gzipped copy only.
