Informix vs. PowerBuilder

I wonder if somebody could help me with a problem I have using PB vs. Informix. I am working with PowerBuilder Enterprice 4.0 Informix OnLine 5 and I-Net 5.0 Unix on a Unisys machine Sometimes and sudenly, I-net reports the error num. -457 that means something like "The server have stoped all process" and my PB aplication is disconected from informix. This error happen very often - so you can imagine what the users are saying! (Other error like "To many hosts variables are passed to the server" were also reported, but we have avoided it using a tric in PB!) Trying to solve the -457 error we have made the changes in the system parameters (Unix and Informix): Informix Parameters: SPINCNT Unix Parameters: The ones related with semafores The ones related with shared memory segments size No we are thinking of changing some parameters related with sockets in Unix.
