Subject [users@httpd] Apache keeping open deleted files
Date Mon, 18 Apr 2016 05:25:42 GMT
Hi,

While reviewing filesystem usage we noticed lots of deleted files still
open by Apache, as reported by lsof. Some example lines are below.

Can anyone advise why Apache is keeping these files open, and if there's
anything we can do about it? I have verified that the process numbers
listed are still existing processes.

The server is running Apache 2.4.7-1ubuntu4.8 on Ubuntu 14.04 server,
64bit. Thank you in advance.
