No server process...

Hi

I'm running a protocol that uses some database connection, R and SGE and it was working last night however when I try and run the first process in the protocol that queries data from a database it gives me a No server process message.

If I take those two components and put it into a new protocol it runs fine.... When I rebuild the entire protocol from scratch along with the global parameters it works again.... Has anyone had this problem with protocols getting corrupted?

cheers
