Problem in Windows NT - Please help...

I'm having some problems with my machine. I have Informix 7.30 TC5 installed on Windows NT 4.0 Service Pack 3. The error described on the configuration file ocurred 7 times in the last 10 days, and we don't know what's happening. I hope somebody can help us. Thanks in advance. -- Paulo Roberto Marelli de Amorim TS&0 Consulting Brasil File created on temporary area: 23:38:44 23:38:44 Informix Dynamic Server Version 7.30.TC5 Software SerialNumber XXXXXXXXXXX 23:38:44 Assert Failed: No Exception Handler 23:38:44 Who: Session(503920, informix@, 0, 0) Thread(9, soctcplst, 0, 1) Exception at Addr: 0x69875f, TOS: 0x12057a5c, FP:0x12057a60, Exc: c0000005 23:38:44 Results: Exception Caught.
