strace shows you the system calls being made by the program. When it's
hanging for a long time, note the last few lines of output from strace
and let us know what those are. The last one will be the call that is
taking so long to finish.

Hello,
Apologies for cross-posting (this list and martinos-tech), but I think
that by posting here I might be able to reach a few more people who may
have had the problem before and solved it.
I have been experiencing very long load-up times, when running
tksurfer. It can take up to 6 or 7 minutes to load. As far as I can
tell, the application does not have any unusual or slow behaviors once
it finally launches. The problem was not present until Friday, but has
persisted since, and I run it the same now as I did before.
Paul Raines mentioned on martinos-tech that there used to be a problem
where the SUBJECTS_DIR was searched recursively and it would slow down
the loading times for a comparable length of time. Can anyone confirm
that this is still what tksurfer does? When I run it, I source the
latest development version.
If the problem is not the long search and file checks, then what could
be the source of the delay?
The command is: tksurfer average7 lh inflated
The output is normal and I'm running it from
/space/ventzl/1/users/SUBJECTS_DIR/
This is the tksurfer /usr/local/freesurfer/dev/bin/tksurfer
The initial output is:
surfer: current subjects dir: /space/ventzl/1/users/SUBJECTS_DIR
surfer: not in scripts dir == using cwd for session root
surfer: session root data dir ($session) set to:
surfer: /autofs/space/ventzl_001/users/SUBJECTS_DIR
Then it hangs for 6 minutes or longer, and launches the tk gui.
When I strace it, there is trace information to show initially, and then
there is the text output I mentioned above, but during the waiting
period there is no output from strace at all.
Thanks in advance,
Rob
