Errors -242 and -211 help needed, configuratoin file included

Hi, I've already sent a message to this list, but in this I include my configuration file. I have installed informix On-Line 4 on 2 RS/6000 under AIX 3.1. In one machine there's no problem, but the other..... Suddenly I get this messages while running an application or the isql: SQL error -242Cannot read system catalog (systables) SYSTEM error -101 File is not open. Only once I got this: SQL error -211Cannot read "table name" SYSTEM error -101 File is not open These errors appear whenever they want, there's nothing special between a query done when no error appears and when it does appear. What can I do? I read somewhere in the list that this may be a bug and somebody supplied some bug numbers. Can somebody explain this for me? Here is my configuration file. I'd gladly change it if this is the solution.
