Attention is currently required from: laforge, pespin. Hello Jenkins Builder, laforge, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/erlang/osmo_dia2gsup/+/40127?usp=email to look at the new patch set (#2). The following approvals got outdated and were removed: Verified+1 by Jenkins Builder Change subject: osmo_dia2gsup: set sndbuf/recbuf explicitly for SCTP ...................................................................... osmo_dia2gsup: set sndbuf/recbuf explicitly for SCTP When opening an SCTP socket on Linux, Erlang/OTP does set its own default SO_SNDBUF/SO_RCVBUF values if the respective socket options (sndbuf and recbuf) are not given to gen_sctp:open/N explicitly. For some reason, the default RCVBUF size (1024) is much smaller than the default SNDBUF size (65536), and both are well below modern Linux defaults. Such a small RCVBUF size becomes problematic when the remote peer is sending large packets. Let's explicitly set both sndbuf/recbuf parameters to 65536, allowing the user to overwrite this default via the environment parameters. For more details, see https://github.com/erlang/otp/issues/9722.
