That would be typical of an application that is stable in memory
allocation (no leaks), but has a pattern of allocation that causes
fragmentation. I have that a lot in network applications that use
buffers for I/O, and I usually either call Gc.compact once in a while,
or I set max_overhead in Gc.control to something like 50.
For example, one of the servers behind shopping.nbci.com uses anywhere
from 300M to 500M, but I have to leave the compaction to avoid
swapping.
