After bisecting for hours, l only had ten revisions left to test.
There was this commit that caught my eye:
------------------------------
commit c96fd3d461fa495400df24be3b3b66f0e0b152f9
Author: Ilpo Järvinen <ilpo.jarvinen@helsinki.fi>
Date: Thu Sep 20 11:36:37 2007 -0700
[TCP]: Enable SACK enhanced FRTO (RFC4138) by default
------------------------------
This change sets the value of "tcp_frto" to 2 by default.
If I reset it to zero, the connection works immediately.
@Dâniel Fraga: Does disabling tcp_frto work for you, too?
Disabling tcp_sack makes no difference. To summarize the situation,
I had two different cases of stalling TCP connections, both connecting
to busy SMTP relays servers which probably drop some packets here and there.
I can easily reproduce the problem, so how do we go from here?
Cheers,
Thomas
