Its a case of having sufficient memory in the atomic pools. Its possible to do some ugly quick kernel hack to make the pool commit less likely to be a problem. Ultimately its an insoluble problem, neither SunOS, Solaris or NetBSD are infallible, they just never fail for any normal situation, and thats good enough for me as a solution -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
