Thanks, Paul. I still can't stop it hanging, but I've resolved the bug I was tracking anyway. We have some totalview licences here, but I tend to prefer gdb. I remember you saying you worked on DDT. Nothing like favouritism!

The other option is to use a parallel debugger such as DDT or totalview - both are commercial but you can get a trial license. Note: I'm biased towards DDT as I used to work for Allinea and was one of the original developers!

I normally work with gdb and ParaView in serial client-server mode, which works fine. However, I'm now trying to debug the client-server mode when run in parallel using MPICH2 and I'm encountering issues. I've tried the following: (1) Run parallel pvserver first -> attach gdb to a process id -> start paraview client -> connect to server -> Result: client connected message appears then the client hangs. >>> mpirun -np 16 /path/to/ParaView-3.10.1-Debug/bin/pvserver >>> gdb --pid xxxx >>> paraview >>> (connect to client) (2) Run parallel pvserver first with gdb -> Result: pvserver does not start properly (no port message or waiting for client). >>> mpirun -np 16 gdb /path/to/ParaView-3.10.1-Debug/bin/pvserver gdb>> run >>> (server hangs) I tried the second option just in case it worked, but I was sure (and previous posts on the mailing lists showed) that the first option would work. I am using ParaView 3.10.1 Release built on CentOS5.4 using standard OS libraries with MPICH2.1.3. Is there something I've done wrong here? Any suggestions?
