Informix : Bladelet Exec causes IDS Engine to crash !!

Hello, I use the Bladelet Exec to execute Dynamic Sql from SPL, I downloaded it from : http://www-106.ibm.com/developerworks/db2/zones/informix/library/demo/ids_exec.html but after some hours of use it causes the IDS 9.30 Server to crash. Here is the message in online.log : 16:48:34 Assert Failed: No Exception Handler 16:48:34 Informix Dynamic Server Version 9.30.FC3 16:48:34 Who: Session(189, import@a31c2e6, 308, 514221928) Thread(211, sqlexec, c00000001ea3e480, 1) File: mtex.c Line: 420 16:48:34 Results: Exception Caught.

I compiled this DataBlade under HP-UX 11.11 on a L3000 HP 4 processors Server having 4 Go of memory. Now it's turned off to avoid these several crashs, but it is very usefull to me to execute dynamic sqls. Can you tell me if this is common to this function ? Is there a solution to this problem ? Is there a new version or a commertial versionof this bladelet ? Thanks .
