NEED HELP WITH INFORMIX ONLINE

Hello out there, i need help with an informix-problem that takes all my energies for about more than one week. We have to realize a project that uses INFORMIX-ONLINE. We are using the following releases of INFORMIX for development.. INFORMIX ESQL/C V7.1B00 INFORMIX ONLINE DYNAMIC SERVER V7.1B00 INFORMIX DEVELOPMENT SYSTEM V6.0B00 The platform we use is a SNI-RM600. The problem looks as following: I have an application which has to read data from two different tables, and afterwards write data into a third table. For database-access we use a library which can perform sql-statements that are generated at the runtime of the application. When i start the appliation it works good until it reaches the insert statement. The sqlca.sqlcode has a value of -404 after trying to perform the insert statement ($execute ......). In the logfile of the database are the following statements. 18:38:29 Pool = 0xaa02010, Pool name = 4, Blkhdr = 0xab0b27c 18:38:29 Block magic is 13, expecting 13 18:38:29 Possible memory block trailer corruption 18:38:29 mtshpool.c, line 2536, thread 36, proc id 2698, ConditionFailed (CHEC K_ALLOC_BLOCK), In (mt_shm_free) Thread(36, sqlexec, 0, 1). 18:38:29 PANIC: Attempting to bring system down and then INFORMIX-ONLINE is gone (Means that all 'oninit'-processes are down). I would be very pleased at your tips (ASAP). Please contact me via e-mail.
