This looks a little odd. On our systems, the permissions on .mctmp
are:
drwxrwxr-x 3 mcidas ustaff 512 Jan 31 11:50 .mctmp/

OK, I did. I ran into the same problems you did and more.
To begin with, I cleaned up a preexisting McIDAS-X session:
<login as mcidas>
cd .mctmp
rm -rf 100
ipcrm -m 100
Since I was suspicious about the permissions on ~mcidas/.mctmp, I did
the following from snowball:
<login as mcidas>
rmdir .mctmp
mkdir .mctmp
Now the directory permissions on .mctmp are what I would expect. The
next thing I tried to do from the command line was:
setenv MCDATA /software/mcidas/mcidas7.6/data
setenv MCPATH ${MCDATA}:/software/mcidas/mcidas7.6/src
setenv MCGUI /software/mcidas/mcidas7.6/src
setenv PATH ${MCGUI}:$PATH
cd mcidas7.6/data
dmap.k AREA
This hung in the way that you originally reported, so the change to .mctmp
was of no help.
I then did:
cd ../src
ldd dmap.k
and got:
/software/mcidas/mcidas7.6/src% ldd dmap.k
libgen.so.1 => (file not found)
libsocket.so.1 => /usr/lib/libsocket.so.1
libnsl.so.1 => /usr/lib/libnsl.so.1
libm.so.1 => /usr/lib/libm.so.1
libF77.so.4 => /software/SUNWspro/lib/libF77.so.4
libM77.so.2 => /software/SUNWspro/lib/libM77.so.2
libsunmath.so.1 => /software/SUNWspro/lib/libsunmath.so.1
libc.so.1 => /usr/lib/libc.so.1
libdl.so.1 => /usr/lib/libdl.so.1
libmp.so.2 => /usr/lib/libmp.so.2
So, on snowball libgen.so can't be found.
Over on twister, an ls showed:
cd mcidas7.6/src
ls -l dmap.k
dmap.k: Stale NFS file handle
An ldd shows the same thing:
ldd dmap.k
ldd: dmap.k: cannot open file: Stale NFS file handle
So, it looks like there might be a automounter problem of some kind.
In trying to figure out why McIDAS routines were waiting, I noticed
that they were not creating a lock file in /tmp. On twister, the
/tmp/mclock directory was not even being created. To test if creating
one would help, I made one by hand. This had no effect unfortunately.
>Its probably something very easy and silly that I missed but am not seeing.
If it is something silly, then I can't see it either! I bet, however, that
it has something to do with either shared memory, or automounted file
systems. What I would do to test this is reboot both snowball and twister
in sequence to see if this is beneficial in any way. Since I realize that
this would be cause a big inconvenience during the day, I don't expect
that you could get around to doing this for awhile
>Thanks for your help!
If I could have pinpointed the problem, I would feel a whole lot better.
I will have to revisit your machine later this evening when the net
is quieter. I ran into what you were telling us: connectivity is
pretty bad.
