Hi, I suppport a system where the /tmp file system fills up as shown by df -k, however, I cant find any files of significant size. Yes, I have used the "Troubleshooting full filesystems" document. Running a number of find commands does not show what is filling up the filesystem (For example find /tmp -xdev -mtime 0). The largest file is 1.37 MB. Running fuser shows only the cron process using /tmp. There are no cron jobs or applications using the directory. An IPL of the RS6000 brings the filesystem back to about 5 % used space, then it steadily grows to near 100% over several weeks. Again, an IPL takes it back down to 5 %. This cycle has been going on for several months. It appears to have started after an upgrade of the OS from 4.33 to 5.2. ML is 9.

Any ideas?

Corrupted filesystem? Have you tried remounting/fsck?

Hi, I haved rebooted the box which would have remounted the file system. I have also run fsck and it showed no errors. thanks for the suggestions.

Try lsof. You may have an application that opens and writes files which are then removed by some other process. As long as at least one process has the file open, the space on disk is not freed up even though the files directory entry has been removed.
