Description Christopher Beland 2011-04-08 15:10:34 UTC

Old sockets are accumulating in /tmp and nothing is cleaning them up.  This is an excert of "ls -t" in /tmp from today:

The keyring directories look like this:

keyring-9AU1YO/:
socket=  socket.pkcs11=  socket.ssh=

The daily cron job that tmpwatch runs should be made more intelligent.  At the very least, it should be able to tell that any usage of these sockets predates the last system boot; I don't think it's possible for anything to still be using them.

Comment 1 Miloslav Trmač 2011-04-08 15:21:08 UTC

Thanks for your report.

tmpwatch does not remove sockets because it can not detect whether a socket file has been used recently only using file times (see #114969).

Looking for timestamps that are older than last system boot is a great idea, something to try for F16.

Comment 2 Miloslav Trmač 2012-05-25 23:51:08 UTC

Removing old enough sockets was finally implemented in tmpwatch-2.11, now built for rawhide.
