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
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.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. See description
which kernel was this ?
and running unknown stuff as root indeed can just hang your box... root has that
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.
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
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/
