Richard Scheffenegger <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #2 from Richard Scheffenegger <[email protected]> --- Daniel, If you can deterministically reproduce this, that this is probably what Gleb was looking for. It is likely that this is an instance where the retransmit timer is active on a closed (or closing) session, where the socket buffers were already freed... The BT certainly looks like this - the open question is, why not all outstanding timers get cancelled when a session is closing - one codepath seems to be missing the relevant cleanups. (This appears to have been exposed by my recent change of not discarding the SACK scoreboard on an RTO - SACK retransmissions do re-arm the RTO timer.) If you are looking for a quick workaround, we have one, but would really appreciate your help into understanding the actual root cause (codepath where session closure is not properly cleaning up). -- You are receiving this mail because: You are the assignee for the bug.
