I can only assume that you are getting an out of disk space type of error.
This may be happening if you are uploading large files. Jenkins is typically using the temp space of the system account under which Jenkins is running as an upload area. Sometimes there are limitations to this resulting in out of disk space errors.
You will need to assign the TEMP or TMP space for the system account to a disk that has plenty of space. How you do this depends on your OS.
