Summary0002436: OOM on game-loading with many cpu-cores
Descriptionwith 12 cores + 6 GB RAM a user seems to get crashes because of OOM (?)

http://springrts.com/phpbb/viewtopic.php?f=11&t=25047&p=486825#p486825

lowering HardwareThreadCount fixed the crashes


so, limit the count to threads depending on #cpu core, memory + map width + map height to avoid such crashes?

 Being a 32-bit application Spring can never allocate more than 4GB of memory for itself, even if a machine has much more and/or runs a 64-bit OS. The real problem though is fragmentation. A map like Throne "only" requires ~100MB per CPathFinder instance, but getting N such blocks in a row is less likely as N becomes larger. For N=12, you're most often out of luck.
