At least one of these should work. Before publishing this problem I had the same idea. Primary this program used SHM-connection(default SHMBASE=0x2000000). But I tried TCP-connection and the same problem still remains. The server is configured for TCP- and SHM-connection (default SHMBASE=0x2000000). I think if only the (via-tcp-connecting) client has this problem, the SHMBASE-address of the server does not matter. Any other ideas, recommendations ? TIA Ruediger
