MFGwrk803 lbia file keeps growing

Have a file e:\epicor\mfgwrk803\lbia04632 that is 128,710,492 Kb and it is still growing, file is locked and won't let me delete it.
Found the vbs file on Friday to clear out directory and set it to run daily at 8 p.m. and clean out everything 2 days old. Only have 20 gb free on the drive. Looked at task manager and I didn't find a PID with this number.
What else do I look for, not sure this will stay running until morning when support opens....

Also stopped Test and Training databases.

Thanks,

James
