#1393 Webmin runs system out of memory
This bug report might not be related to webmin but
needs to be at least detailed since it looks like it's
been reported before here
Recently I update a Redhat 8 install to Redhat 9 (via
Yum). The box is an old Dell Poweredge 6100/200 with
1GB memory and 4 CPU's. Everything seemed fine but a
after about 48 hours the machine locked up. I managed
toi get into it and found that it was totally out of
memory and swap. This happened several times during the
next few days before I tracked it down to the
miniserver.pl process.
Here are some details.

I'm going back to look at it again right now but I'm
pretty sure its something in the SSL setup.

The loop (or whatever it is) seems to occur at log out.
I post more regarding this is I figure it out.

Upgrading Net::SSLeay seems to have fixed this issue.

Some people have reported a problem like this when webmin is
running in SSL mode, with certain versions of OpenSSL.
Unfortunately, the bug seems to be inside the OpenSSL
library, and so cannot easily be fixed ...
Does it still happen if you turn off SSL?
