I have an RSE account with OLM and I typcially have about 2 - 2.5 gig free of disk space on my server.

Last week my free disk space was 0, and I found that I have about 2 gig of files in my /tmp dir.

These are pretty big files (one was 400 meg) and they all end in .wrk

What are these files?

Can I delete them?

Are you using mod_gzip???

I sure am. Is this a problem?

I did some research on the web about mod_gzip (thanks for the info sitekeeper) and I do think this caused the problem.

I made a few changes to my httpd.conf like setting maximum file size and excluding a few additional mime types (audio, video, etc.) and I hope this will correct the problem.

Did you fix your problem? If so, it might be helpful to others if you post what changes you made.

The problem does appear to be solved, however I will continue to observe it for several weeks to be certain.

In my case I made a few changes to httpd.conf.

First I set the maximum file size:

mod_gzip_maximum_file_size 100000


Then I excluded certain mime types that don't compress very well anyway:

mod_gzip_item_exclude mime ^image/.*
mod_gzip_item_exclude mime ^audio/.*
mod_gzip_item_exclude mime ^video/.*
mod_gzip_item_exclude mime ^multipart/.*


And finally, make sure this line is present (mine already was):

mod_gzip_keep_workfiles No
