GC error messages

The GC garbage collector is used by Macaulay 2 for its memory management. It is reponsible for getting more memory from the operating system when needed for storage of data, and for recovering areas of memory no longer needed.

Here is a list of error messages you may see from it when it aborts the program, due to lack of memory or related problems. Typically, the only recourse for the user is to increase the memory available to the program.

• Insufficient space for initial table allocation
• No space for lwp data structures
• Out of memory
• Too many exclusions
• Too many heap sections: Increase MAXHINCR or MAX_HEAP_SECTS
• Too many root sets
