Description Ken Olum 2003-05-09 15:28:49 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.0) Gecko/20020529

Description of problem:
I installed FlexLM to manage floating licenses for the microimages X server from
ftp://ftp.microimages.com/pub/mix/flexlm-linux.tar.gz, with the following
license dat file:

SERVER cosmos.phy.tufts.edu 009027dc4ccd
USE_SERVER
VENDOR lmdmcrimgs "/usr/local/flexlm/lmdmcrimgs"
FEATURE mix lmdmcrimgs 4.000 permanent 10 0 ck=3D172

The hostID is correct for the machine, but the checksum for the product is not
the right one, because we sent them the wrong hostID when we got a license.

When I started lmgrd as root, my machine became totally wedged: no mouse
tracking, no return of ICMP echoes, no response to Ctl-Alt-Del, etc.
Of course I don't know what the program is doing, and it was running as root, so
it could be a program error, but I suspect a kernel problem.
The problem occurs on more than one machine (with the correct machine name and
hostID in the file) and in both 7.1 and 7.2.

which kernel was this ?
and running unknown stuff as root indeed can just hang your box... root has that
power

Comment 2 Ken Olum 2003-05-09 16:32:10 UTC

The kernel is 2.4.18-27.7.

It could of course be a problem with the program.  I am reporting it also to
Microimages.  The reason that I suspect a kernel problem is that one wouldn't
think the normal stuff that would be in a program to read files and check
license codes would lead to crashes.  But of course I understand that there's no
limit to the ability of some random programmer at some other company to screw up.

Comment 3 Bugzilla owner 2004-09-30 15:40:53 UTC

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
persists.

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
