Dave,

>After taking a break from messing with McIDAS (hoping that if I left it
>alone it would fix itself!) I decided to get back into it.  I followed
>Mike Schmidt's advice and patched up both snowball and twister to the
>recommended patch sets and nfs patches.  I also messed around with how

>read/write, and making sure the McIDAS user was NOT automounted on
>twister, since the /software filesystem is already mounted on boot.

OK.

>Anyway I created a soft link to /tmp/mctmp for the
>/software/mcidas/.mctmp directory, unfortunately mcenv STILL hangs.

On which system?  I had already done this to prove that McIDAS worked
previously.

>I'm not sure how Mike got McIDAS to work by doing this last time.

Actually, I got things to work.  The idea is that McIDAS needs to create
files in directories created for each McIDAS session under a .mctmp
directory in the user's account.  Given that the locking was not working
with your NFS mount setup, I did the following:

o make sure all McIDAS things in the account were inactive (i.e. no sessions
  running

o cd ~mcidas
  rm -rf .mctmp
  mkdir /tmp/mctmp
  ln -s /tmp/mctmp .mctmp

Weird.  Can I get the login again?

The truss you sent along indicates hanging in a different spot than
before.  Previously, the system would hang waiting for a lock on the
file mcclean.lock.  Now it is hanging when doing an EU command.  This
_may_ be progress :-)
