This is at least slightly off-topic, but I'm going to ask anyway.

We've had our /var/spool/MIMEDefang directory on a tmpfs filesystem
for quite a while. Every once and a while, mail stops flowing because
the tmpfs filesystem is full. That by itself is strange. It's even
stranger because when I rm -rf /var/spool/MIMEDefang/* (after
stopping MIMEDefang and Sendmail), the disk usage stays the same. I
even made sure that all the mimedefang* and sendmail processes were
killed.

It seems to me that this is either a case of file descriptors being
stuck open somehow or a memory leak in the tmpfs code. In any case,
umount and remounting the filesystem solves the problem as is
expected.

The box is running Red Hat Linux 9. The kernel version is 2.4.20-18.9
from the RedHat RPM. Sendmail is version 8.12.8-5.90 from the RedHat
RPM. I'm running MIMEDefang version 2.34 compiled from source using
GCC version 3.2.2 20030222 from the RedHat RPM (3.2.2-5).

Has anyone seen this sort of behavior?

Thanks,
