This at least shows progress.

Graphics memory is shared memory resident.

The could not clean up message is related to the cleanup process, 'mccheck'
not being able to remove an NFS resource file in ~mcidas/.mctmp/201.

>Needless to say mcidas still hangs.


>Should I recompile or maybe increase shared memory?

I just logged in and am in the process of poking around.  I removed the
~mcidas/.mctmp/201 directory and its contents.  This is something that
I was unable to do before you rebooted.

You have plenty of shared memory configured for this system (the
recommended 512 MB), so you don't need to add more.

As far as recompiling, I am now installing the distribution:

<login as 'mcidas'>
cd mcidas7.6/src
make install.all

and will go from there.  I will be looking to see if anything jumps out at
me after things in their install locations.

OK, here is the bad news:

o after I installed McIDAS, then ROUTE PP BATCH invocations from the ldm
  account started firing off.  This has caused your 'ldm' user to have
  a number of hanging batch.k and nortmapr routines:

  Since I do not have a login as 'ldm', I could not kill them.  To prevent
  more from appearing, I uninstalled the McIDAS binaries.

o the McIDAS stuff is hanging when trying to set file control information
  on a file called mcclean.lock (gets created in the subdirectories of
  .mctmp).  Mike Schmidt and I were looking at your system until he
  had to leave; we believe that the problem is centered on how /software
  is being mounted from snowball.

We traced the sequence of events leading to the hanging condition by

truss ~mcidas7.6/src/mcenv

What we found was:

open("/software/mcidas/.mctmp/42704/TERMCHAR.001", O_RDWR|O_CREAT, 0600) = 4
write(4, "80", 1)                               = 1
close(4)                                        = 0
open("/software/mcidas/.mctmp/42704/GRAPHICS.KEY", O_RDWR|O_CREAT, 0600) = 4
write(4, "80", 1)                               = 1
close(4)                                        = 0
open("/software/mcidas/.mctmp/42704/STRTABLE", O_RDWR|O_CREAT, 0600) = 4
write(4, "80", 1)                               = 1
close(4)                                        = 0
open("/software/mcidas/.mctmp/42704/mcclean.lock", O_RDWR|O_CREAT, 0600) = 4
write(4, "80", 1)                               = 1
fcntl(4, F_GETFD, 0x00000000)                   = 0
fcntl(4, F_SETFD, 0x00000001)                   = 0

The last line is where things are hanging.  the file
/software/mcidas/.mctmp/42704/mcclean.lock was created, but the system was
unable to change something with the file, so it was waiting.  This must
have something to do with how the file system is being mounted.  Mike
said that he would try and take a closer look at things tonight from
home, but I feel certain that he will need root privilege to do anything
