Resolution: The TIBCO InConcert server will fail either to start using IcStart or to stop using IcStop. Worker processes have to be killed using 'kill -9'. No information is written out to the status.log or to the debug.log if on.
This problem will happen when the OS auto mounter fails. On Solaris the loader, ldd, hangs when it gets no response from the automounter. The loader is trying a 'stat' on the file libsocket.so.1 in the original directory it was compiled with. The 'stat' command finds the status of the file along with permissions. You can see this if you run 'truss' on IcStart. You would see the following message 'stat("/home/fiedler/opt/SUNWspro/lib/rw7/libsocket.so.1", 0xFFBEF1B4) Err#2 ENOENT //entry not found'.
The automounterd must be fixed. A reboot may fix the problem. NOTE having a correct LD_LIBRARY_PATH does not affect the hang. There is no way to have the loader not search /home/fiedler.
