The switchtest test creates many kernel threads, an operation which consumes memory taken from internal pools managed by the Xenomai real-time core.
Xenomai 2.x and 3.x series require CONFIG_XENO_OPT_SYS_HEAPSZ to be large enough in the kernel configuration settings, to cope with the allocation requests.
Xenomai 2.x may also require to increase the CONFIG_XENO_OPT_SYS_STACKPOOLSZ setting.
