Error -457 upon Execution of SQL Statement

I sent the following article to c.d.i on March 29.Since I didn't get any articles at all from c.d.i. during the next days I was informed that the news provider server suffered a disk crash.As I suspect that my article didn't reach c.d.i at all I post it again.If someone has suggestions he can directly E-mail me. We have following Problem on one of our clients running Informix Online 5.02.UC8 on DEC OSF/1 V3.0.Upon execution of the following SQL Statement through dbaccess we get -457 error (SQL Engine terminated unexpextedly).The same SQL Statement runs without Problems in our SCO Server. The SQL Statement looks like: SELECT bestellung.*,bespos.*,kunden.matchku FROM bestellung,kunden,bespos,artikel, artgeb WHERE bestellung.fbestnr="340" AND bestellung.finr = 2 AND bestellung.bestnr = bespos.bestnr AND bestellung.besart > 1 AND bestellung.beststatus IN (25,30,35) AND bespos.refnr IS NULL AND kunden.finr = bestellung.finr AND kunden.kunr = bestellung.kunr AND kunden.konto_art = 2 AND bespos.art_num = artikel.art_num AND bespos.gebnr = artgeb.gebnr AND artikel.finr = 2 AND artikel.artnr = artgeb.artnr ORDER BY bestellung.fbestnr,bespos.besposnr If I modify this SQL Statement and remove the table artgeb or use another table instead it works fine ! I also include parts of the tbconfig file from the DEC Server: # Root Dbspace Configuration ROOTNAME rootdbs # Root dbspace nameROOTPATH /dev/online_root # Path for device containing root dbspace ROOTOFFSET 1024 # Offset of root dbspace into device (Kbytes) ROOTSIZE 60000 # Size of root dbspace (Kbytes) # Disk Mirroring Configuration MIRROR 0 # Mirroring flag (Yes = 1, No = 0) MIRRORPATH # Path for device containing rootdbspace mirror MIRROROFFSET 0 # Offset into mirror device (Kbytes) # Physical Log Configuration PHYSDBS rootdbs # Name of dbspace that contains physical log PHYSFILE 1000 # Physical log file size (Kbytes) # Logical Log Configuration LOGFILES 20 # Number of logical log files LOGSIZE 500 # Size of each logical log file (Kbytes) # Identification Parameters SERVERNUM 0 # Unique id associated with thisOnLine instance DBSERVERNAME BKK_Server # Unique name of this OnLine instance # Shared Memory Parameters RESIDENT 0 # Forced residency flag (Yes = 1, No = 0)USERS 100 # Maximum number of concurrent user processes TRANSACTIONS 100 # Maximum number of concurrent transactions LOCKS 10000 # Maximum number of locks BUFFERS 1000 # Maximum number of shared memorybuffers TBLSPACES 1000 # Maximum number of active tblspaces CHUNKS 58 # Maximum number of chunks DBSPACES 8 # Maximum number of dbspaces and blobspaces PHYSBUFF 32 # Size of physical log buffers (Kbytes) LOGBUFF 32 # Size of logical log buffers (Kbytes)LOGSMAX 61 # Maximum number of logical log files CLEANERS 1 # Number of page-cleaner processes SHMBASE 0x800000 # Shared memory base address CKPTINTVL 300 # Checkpoint interval (in seconds) LRUS 8 # Number of LRU queues LRU_MAX_DIRTY 60 # LRU modified begin-cleaning limit (percent) LRU_MIN_DIRTY 50 # LRU modified end-cleaning limit (percent) LTXHWM 80 # Long TX high-water mark (percent) LTXEHWM 90 # Long TX exclusive high-water mark (percent) # Machine- and Product-Specific Parameters DYNSHMSZ 0 # Dynamic shared memory size (Kbytes) GTRID_CMP_SZ 32 # Number of bytes to use in GTRID comparision DEADLOCK_TIMEOUT 60 # Max time to wait for lock indistributed env.

Does anyone have an idea where the problem is ? Thanks in advance Tolis Varnas tvarnas@athena.compulink.forthnet.gr
