ORA-00604 when connect to database

[lsy]

I'm writing PRO C program with oracle 8i. My process first connect to the database with using ora_connect(), proceed the task then diconnect with using ora_disconnect( ). This would always in a loop, recently after few cycle of connect and disconnect, when the next issue connect statement, it was unable to connect and return me ora-00604 and the process end. Even i restart the process, after few cycle also the same return me ora-00604 during the connect.
Is there anyone have an idea how to resolve this?

what makes you create and close so many connections.

my program are in a loop...if it encounter error, it might not disconnect and keep looping in the program, so decided after complete 1 cycle disconnect it.

Can you try the CONNECT and DISCONNECT statements out side the loop. That should work becuase having CONNECT string inside loop is not advisable
