Hi,

I get the following error message each time I reset pvm, and run a program
that uses the group library:

[t40016] libpvm [t40016]: gs_getgstid() failed to start group server: No such file
[t40016] libpvm [t40016]:  could not join group 
[t40016] : Can't contact local daemon

This only happens the FIRST time I execute my program: everything is fine
in the second/third etc. trials, without recompilation/modifications. The
aggravating part is that, since only a few of my processes actually use
the group functions and die in the first execution, all the other processes
hang on recv's, and I have to manually kill them (can't use pvm's reset:
brings back the problem)

Is this something about the setup here at UTK, or am I doing something
incorrectly? The compile and link options I use are:

gcc  -c -g -I/src/icl/pvm/pvm3/include gamma.c 
gcc  -g -o gamma gamma.o -lm -L/src/icl/pvm/pvm3/lib/SUN4 -lpvm3  -lgpvm3 

This problem occurs even with the example group programs provided with
pvm.
