Posting from the Informix-list

Hi,everybody. I need your help for my question. I have a process which is running on a host. It will access local data and remote data on on another host. When it startup, it open the local database, and only when it exit, it will close the local database. This afternoon when it access remote data, it report error 908(attemp to connect remote system failed), and then it wait at that point, it doesn't continue as if it is dead, but the process is still exist by using "ps" command. Finally the only way for me to kill it, and the result of kill is successful.I don't know why. And I have set it's lock mode to wait(SQL statement "set lock mode to wait 5"). Have you ever meet with this error? If so, could you tell me why and how to settle this problem? My running environment is: OS platform is SCO unix 3.2Release 5.0.4, and the Informix is 7.22.UC3. Local database and remote database are all accessed by TCP/IP means. Wait for your help.
