https://bugzilla.mcs.anl.gov/swift/show_bug.cgi?id=690 --- Comment #21 from David Kelly <[email protected]> 2012-02-15 15:13:44 --- It looks like his change only affects transfers between MCS and CI, but perhaps this might provide some insight on what is happening in other situations. --- this would affect only connections sourced from MCS server net (140.221.8.0-140.221.9.255). It has to do with long-term transfers. The longer a transfer continues via TCP, the larger the window size becomes. At some point, the ACKs coming back from the client which keep the dynamic rule in place (reflexive ACLs and stateful firewalls work in a similar way) time out. This cuts off the flow of data from the server to client, which then sees no traffic, times out and the application becomes unhappy. By bypassing the dynamic portion, we keep the flow of traffic happy. -- Configure bugmail: https://bugzilla.mcs.anl.gov/swift/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.
