If you see the error AbortIfEndofStack in
the stack trace file (stktrc-YYYYMMDD-HHNNSS_#.iq),
the thread stack has overflowed.
To avoid this problem, restart Sybase IQ with the server parameter -iqtss set to 300 on 32-bit operating systems or 500 on 64-bit operating systems. On 32-bit systems, you may need to decrease LOAD_MEMORY_MB in order to increase -iqtss. The server startup switch -iqtss specifies thread stack size in KB. If this is not adequate, raise the value of -iqtss by 72 until the problem is solved.
If possible, identify the command that caused the error and forward it to Sybase Technical Support.
