The most likely cause is a memory leak.  You can help track this down by
enabling MALLOC_DEBUG in 'make menuselect' and recompiling.  This adds
the CLI commands 'memory show summary' and 'memory show allocations'.  This
hopefully will show where there's a leak and help you or us track this down.

Another less likely cause is that you have a limit on the amount of memory
that a single user can allocate on the system.
