Channel allocation stress-test

dear holger, i tried your channel allocation stress-test patch for openbsc with osmo-bts-trx. i had no crashes, but it helped me to find a bug in the scheduler. i remember that there was an issue that causes a crash of osmo-bts (sysmobts, trx ?), but i am not sure. if so, can you give me a hint, which test procedure caused a crash? regards, andreas
