 Allocated memory used by NLM programs
Memory from cache is allocated to an NLM program when requested. When
an NLM program is finished using the memory, it releases the memory and
returns it to cache. NetWare also provides a garbage collection process to
recover unused memory. The garbage collector runs in the background, but
you can manually initiate the process if needed. See “Optimizing Garbage
Collection” on page 31.
