IDS 7.30.UC6 crash

Dear Informixers, my development engine (luckily not the production one) has been giving me a strange error since it had to be reinitialized due to a harddisk crash a couple of days ago. The following message appears in the log file: Wed Sep 29 14:40:58 1999 14:40:58 Event alarms enabled. ALARMPROG = '/opt/7_informix/etc/no_log.sh' 14:41:10 DR: DRAUTO is 0 (Off) 14:41:10 Requested shared memory segment size rounded from 588KB to 592KB 14:41:11 Assert Failed: Condition Failed (Bad allocation size (0) forpool 'aio ' (0x21020018)), In (mt_shm_malloc_segid) 14:41:11 Informix Dynamic Server Version 7.30.UC6 14:41:11 Who: Session(0, @, 0, 0) Thread(6, vp 1, 0, 7) File: mtshpool.c Line: 2352 14:41:11 Action: Please notify Informix Technical Support. 14:41:30 See Also: /tmp/af.608e7, shmem.608e7.0 14:41:32 Assert Failed: Condition Failed (Bad allocation size (0) forpool 'aio ' (0x21020018)), In (mt_shm_malloc_segid) 14:41:32 Informix Dynamic Server Version 7.30.UC6 14:41:32 Who: Session(0, @, 0, 0) Thread(6, vp 1, 0, 7) File: mtshpool.c Line: 2352 14:41:32 Action: Please notify Informix Technical Support. 14:41:50 See Also: /tmp/af.608e7, shmem.608e7.1 14:42:09 Informix Dynamic Server Version 7.30.UC6 Software SerialNumber AAC# J288479 14:42:20 Informix Dynamic Server Initialized -- Complete DiskInitialized. 14:42:21 Checkpoint Completed: duration was 0 seconds. 14:42:21 Dataskip is now OFF for all dbspaces 14:42:22 Quiescent Mode 14:43:03 On-Line Mode 14:43:03 Building 'sysmaster' database ... 14:44:01 Checkpoint Completed: duration was 4 seconds. 14:44:15 Logical Log 1 Complete. 14:45:02 Logical Log 2 Complete. 14:45:05 Checkpoint Completed: duration was 2 seconds. 14:45:40 'sysmaster' database built successfully. 14:45:41 'sysutils' database built successfully. As you can see, the error happened immediately upon initializing the engine and disk structures, even before anybody was using the system. I never noticed this until I started getting "file system full" errors today and found /tmp full of "shmem..." files. It turned out that the same error occured several times yesterday and today, each time dumping its shared memory into /tmp. Any ideas where this might come from? I'll save some of the /tmp/af files in case anyone wants to take a look. Platform is Siemens Reliant UNIX 5.43C20, engine version is IDS 7.30.UC6 on a Siemens RM400-330. I cannot ask tech support right now because of a problem with our support contract (nobody can locate the contract number for the development machine, luckily it is intact for our production server).
