[lwip-devel] [bug #24830] Socket never closed sometimes.

[Kieran Mansley]

Follow-up Comment #1, bug #24830 (project lwip):

Looks like one end (not sure which, you don't say which is lwIP) has
advertised a zero window and is refusing to open it.  This is probably
preventing the other end from sending a FIN, and so the connection never gets
closed.  If you can get a packet capture for the whole duration that would be
useful.

You say you're using lwIP from CVS head.  Does that mean it is your own port,
or you're using one of the existing ports?

My guess would be that lwIP is running out of memory due to a bug that is
resulting in packet buffers getting leaked.  You could confirm this by turning
on the lwIP stats and seeing what happens to the available memory when they
are reported.
