( https://gerrit.osmocom.org/9514 Change subject: compact AGCH queue: Drop too msg diff than IMM_ASS_REJ ...................................................................... compact AGCH queue: Drop too msg diff than IMM_ASS_REJ We saw in a recent prod setup a BSC with saturated channels. Further investigation lead to a AGCH queue of 1000 (previous hard_limit) messages, most of them being regular IMM ASSIGN (non REJ). Hence, we also want to get rid of other messages in the AGCH queue (like regular IMM ASSIGN). Furthermore, In this scenario, sending IMM ASS REJ is as important as other messages given than nowadays we support dynamic wait indicatior (calculated based on chan load), which means if we reach the MS, we can tell it to wait for a long time to reach us again, which is desirable.
