I am having a rather urgent problem. Sys is filling up with or with out users logged in. the problem sustains itself for about an hour and then returns to normal. The largest file on the volume is an 18MB file. The problem arose about 4 months ago, and thought that it might be a possible controller failure, since it is reporting space incorrectly. I have had two other Net Admins look at the server while the problem is occuring and could find no stray nlm going crazy. for the past 4 months this has been occuring on saturdays from 11:30p to 12:30a. there are no other processes going on other than file and system maintnance done by netware. Today it has broken this trend and started at 9:30 and went for only 20 minutes and then returned to normal opperation. Compression was turned on when server was installed 3-4 years ago, before I became admin. Any assistance will be helpfull. Thanks
