Have you tried lsof?

Any processes using files there may have them closed. Are there any recent accesses or modifications there?

The filename "sqlnet.log" suggests this is very likely an Oracle client log file. The directory name would suggest it might be related to application "elink".

The configuration parameter LOG_DIRECTORY_CLIENT in a sqlnet.ora file will determine where the sqlnet.log files will be written.

You should talk to the people responsible for the "elink" application and see if the log belongs to them and if they really need the log. If the log is required, you should together estimate the required disk space based on their requirements and the growth rate you've seen. Then you should make the necessary arrangements for getting a suitable location and amount of disk space for the logs (e.g. referring them to an appropriate manager, if necessary for getting the permission to order more disks/LUNs).

It also might be caused by a temporary diagnostic logging that has accidentally been left on for too long. If that is the case, the application people will most likely say something like "oops, sorry, we will disable it right away."

lsof should be able to tell you who has /var/tmp/oradiag_elink/diag/sqlnet.log open.

>for both how do it that

find /var/tmp/oradiag_elink/diag \( -mtime -1 -o -atime -1 \) -exec ll -dt +
find /var/tmp/oradiag_elink/diag \( -mtime -1 -o -atime -1 \) -exec ll -dtu +

Oops, I had some missing spaces and "-" above. Please try the edited commands again.

You may have to specify a specific file. I.e. /var/tmp/oradiag_elink/diag/sqlnet.log.

For my test case, the directory only showed up if it was "cwd". Otherwise I had to list the file that was opened.
