virtfs lock file issue intermittenly affecting 1 cron job

I have been getting the virtfs lock issue on one weekly cron job that runs once a week intermittently for almost 6 months.

attempt to lock file /home/virtfs/_lock/507 timed out after 25 attempts; lock still held by pid 9933
Could not create lock file: /home/virtfs/_lock/507

What's stranger is while I am running a huge number of cron jobs on the server this is one of the simplest. its a a wget fileswitch.php cron job that renames 3 files to old and renames the new files created by the client to current. This job and only this job has encountered this problem and there doesnt appear to be any answers yet on a fix. removing the lockfile is not an option as this is a cron job intended to switch time sensitive material each week, further, the lockfile never exists when I check the server.

I am well aware there is another (merged) thread on the issue however nothing in the thread applies to this situation.
