#1132 Cloning a Webmin user causes the server's CPU to be 100% con
I am using Suse Enterprise version 8 (UnitedLinux 1.0)
on Compaq ML370 hardware (Xeon CPU's).
Webmin is 1.09 running in SSL mode.
After I set up a new webmin user (i.e. other than the
admin user), and then try to clone this user, I get a
message in the browser that the restart of the webmin
server has failed, and then the server becomes
unresponsive and appears to have hung.
In fact, there is a perl process that's taking almost 100%
of the CPU. Attached is a file listing the processes on
the machine after the event. You'll see that there is a
defunct "miniserv.pl" not to mention two apparent
instances of webmin running. Normally of course we just
see a single webmin process running on the machine.
The webmin process pid 571 is the one that's soaking
the CPU, and the attachment also includes an output
from the "top" utility, sorted by CPU usage, that shows
that this process is taking 99.9% of the CPU.
Trying to kill pid 571 did nothing, and a kill -9 571 did
nothing either, so I had to reboot the machine.
I get the same behaviour on 3 different servers, which
are similar but not identical. One is a single 2.4Ghz, one
is a single 2.8Ghz and the one that I obtained the
attachments from is a dual 2.8Ghz.
Reading through the already-reported issues, I noticed
something similar from somebody using IE 6 so I
repeated my steps on all 3 machines, but this time
using Conqueror 3.0.3 as my browser. In this case,
all "clone" operations worked perfectly, leading me to
suspect that IE indeed is part of the issue. I'm running
6.0.26 with 128 bit encryption.
I felt that I should report this even though IE apprears to
be the problem, because there may be something that
still could/ought to be done on the webmin end. It may
also benefit others who can at least work around the
issue by using a different browser.

Some other people that reported this problem have found that
it is caused by the interaction between IE and a particular
version of OpenSSL.
You should try upgrading OpenSSL to the latest version, and
also re-installing the Net::SSLeay perl module.

That is exactly the same problem i have, diference is i use
Stunnel, not the native ssl of the webmin, and happend with ie
6.0 sp1 and opera (whatever ident i put)and mozilla 1.5 RC2,
and by the way, where a i can find the Conquer 3.0.3 for
windows??
