Defaulting to 0, this can be set to 1 to enable 2.0.x-like behavior, which
is less efficient but avoids exposing bug #4083814 in versions of Solaris
prior to 7.0. Alternatively, if you are able to patch your Solaris box(en)
this problem should be fixed by patch 105529-05.
Symptoms are sessions that hang at the very end of data transfers of
certain sizes if the packets arrive out of order (because Solaris forgets
to reply to the FIN flag). On a very good network connection this is hard
to reproduce. It has been well-documented for FTP (with a Solaris
2.5.1/2.6 client and a Linux 2.2.x server) but probably affects HTTP as
well.
Due to the wide use of the afflicted versions of Solaris in
firewalls/proxies, I recommend turning on this workaround on any major FTP
server running on the 2.2.x kernel (and probably HTTP servers as well,
though it has not been proven to affect HTTP behavior -- yet).
