Look at the host's /proc/sys/vm/max_map_count - the default is 64K, which, given UML's propensity to map memory one page at a time, covers 256M of resident memory for a UML process. I'd say double or quadruple it, depending on how much memory you think a process can use. To be absolutely safe, make it big enough to cover all of a UML's physical memory, since a process RSS can't exceed that. Jeff -- Work email - jdike at linux dot intel dot com |
