lock table overflow

hi i'm running ods7.23uc1 on hp-ux10.20. this application is an off-the-shelf manufacutrin gpkg which runs on top of informix. whenever a particular trnasaction the application bombs out with the errors below: %SQLCODE: -244 Could not do a physical-order read to fetch next row. %SQLERRD2: -134 ISAM error: no more locks and in looking at the log file , i saw this error: 19:13:32 Lock table overflow - user id 102, session id 47 i'm wondering if anyone has any ideas on this. i did do oncheck on the tables and indices the sql was after, and it came back okay. i'm attaching my onconfig file. #************************************************************************** # # INFORMIX SOFTWARE, INC. # # Title: onconfig.std # Description: INFORMIX-OnLine Configuration Parameters # #************************************************************************** # Root Dbspace Configuration ROOTNAME root_dbs # Root dbspace name ROOTPATH /PRD1/root # Path for device containing root dbspace ROOTOFFSET 10 # Offset of root dbspace into device (Kbytes) ROOTSIZE 499980 # Size of root dbspace (Kbytes) # Disk Mirroring Configuration Parameters MIRROR 0 # Mirroring flag (Yes = 1, No = 0) MIRRORPATH # Path for device containing mirrored root MIRROROFFSET 0 # Offset into mirrored device (Kbytes) # Physical Log Configuration PHYSDBS phy_dbs # Location (dbspace) of physical log PHYSFILE 95000 # Physical log file size (Kbytes) # Logical Log Configuration LOGFILES 9 # Number of logical log files LOGSIZE 30000 # Logical log size (Kbytes) # Diagnostics MSGPATH /apps/informix/log/wsm_prd1.log # System message log file path CONSOLE /apps/informix/log/console_prd1.log # System console message path ALARMPROGRAM /apps/informix/etc/no_log.sh # Alarm program path # System Archive Tape Device TAPEDEV /mis/dbsave/comets.db # Tape device path TAPEBLK 16 # Tape block size (Kbytes) TAPESIZE 2000000000 # Maximum amount of data to put on tape (Kbytes) # Log Archive Tape Device LTAPEDEV /logsave/comets.log # Log tape device path LTAPEBLK 16 # Log tape block size (Kbytes) LTAPESIZE 2000000 # Max amount of data to put on log tape (Kbytes) # Optical STAGEBLOB ,1 # INFORMIX-OnLine/Optical staging area # System Configuration SERVERNUM 1 # Unique id corresponding to a OnLine instance DBSERVERNAME wsm_prd1 # Name of default database server DBSERVERALIASES penang_prd1 # List of alternate dbservernames NETTYPE ipcshm,1,50,CPU # Configure poll thread(s) for nettype NETTYPE soctcp,1,50,NET # Configure poll thread(s) for nettype DEADLOCK_TIMEOUT 60 # Max time to wait of lock in distributed env.
