open file?

[Prashant Zanwar_4]

I have some open files under /tmp which is showing file system full,

bdf /tmp
Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol5 2048000 2048000 0 100% /tmp

du -sk /tmp
6450 /tmp


Is there any way to know what is causing it, i tried lsof +aL1 /tmp, below is output -

Thanks for replying

It seems everything is in your lsof output.

It seems you have several programs all writing to the 2 Gb file with inode 19042.

If you can't find it using ll, you might be able to use find(1), unless the file was unlinked:
$ find /tmp -inum 19042

hi Prashant,

See the lsof output, there are programs that locking your /tmp. I believe the user oazctes1 is executing some programs?

or what is FNDLIBR do ? Please check with your dba if this is a normal behaviour ?

hi Prashant,

See the lsof output, there are programs that locking your /tmp. I believe the user oazctes1 is executing some programs and the process is locking your /tmp space.

/tmp 100% full, may impact your other operation, please plan to add more /tmp space.

Dear Prashant,

only the DBA guy can help you in this regard,becaz the user "oazctes1" is executing some programmes and you can see it is keep on increasing .Before Adding space to tmp (not good always to add space),pls discuus with DBA ,and confirm what is causing this filesystem to full.
