Hello. I just checked your post on NAMD Wiki. I don't run NAMD on my box, but
some recurrently aborted runs and the message "Segmentation fault" is what I
used to get using CHARMM. I'm running Fedora 3 on x86_64 architecture and,
according to CHARMM users/developers, this is an issue with the way Fedora
The solution they came up with is to increase the maximum stack size. If you are
also using Fedora and run the command "ulimit -s" you will probably get a number
like 10240, so all you would have to do is set it to "unlimited" (or to a really
big number) with "ulimit -s unlimited" (or "ulimit -s some-big-number") before
Hope this helps.
