9512fe850e98fdd448c638ca63fdd92a8a510255ahl * ASSERTION:
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * Checks that setting "bufresize" to "auto" will cause buffer
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * allocation to succeed, even for large aggregation buffer sizes.
9512fe850e98fdd448c638ca63fdd92a8a510255ahl *
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * SECTION: Buffers and Buffering/Buffer Resizing Policy;
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * Options and Tunables/aggsize;

9512fe850e98fdd448c638ca63fdd92a8a510255ahl * NOTES:
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * On some small memory machines, this test may consume so much memory
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * that it induces memory allocation failure in the dtrace library. This
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * will manifest itself as an error like one of the following:
9512fe850e98fdd448c638ca63fdd92a8a510255ahl *
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * dtrace: processing aborted: Memory allocation failure
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * dtrace: could not enable tracing: Memory allocation failure
9512fe850e98fdd448c638ca63fdd92a8a510255ahl *
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * These actually indicate that the test performed as expected; failures
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * of the above nature should therefore be ignored.
