Novell eDirectory 8.8 for NetWare 6.5
Novell NetWare 6.5 Support Pack 6
Running out of disk space
eDirectory 8.8.2 FTF2 or newer has the fix for the problem in question and can be downloaded at: https://download.novell.com/patch/finder/
During troubleshooting we noticed that a file in the SYS:\TMP\DSSNMPSA_LOG.TMP was taking about 6GB, which was approximately the free disk space before this file got created/generated.
If we try to delete the file, and comment out DSSNMPSA.NLM in the AUTOEXEC.NCF, then restart the server all will work fine until we start the NLM again, which will behave like before, creating the file and taking about 1GB per min.
