Resource issues may include insufficient disk space, insufficient
number of threads, thread stack overflow, and unused system resources.
Insufficient Disk Space
The SAP Sybase IQ server does not wait for additional space on an out-of-dbspace condition, but rolls back either the entire transaction or rolls back to a savepoint.
Monitoring Disk Space Usage
You can use an event handler to monitor disk space usage and notify you when available space is running low.
Insufficient Threads
The required number of server threads may not be available for your query.
Stack Overflow
You may experience problems if the thread stack overflows.
Insufficient Buffers
If the resource manager determines that there is not enough cache to complete an operation, the operation is not started, and Insufficient buffers is returned.
