Event 157: wait for object to be returned to pool

The Adaptive Server memory manager allocates memory for storing data describing a wide range of internal objects from separate memory “pools.” When a pool’s available memory is low, requests for additional memory may be delayed until another operation returns memory to the pool. When this occurs, the requesting process must wait until more memory is available.

Event 157 occurs when a process most wait for memory to become available before allocating the object’s data.
