Isn't that done automatically anyway?
BUT, there appears to be a server setting for lighttpd
'max-keep-alive-requests' (default 128 - what is it on ours?) after
which the connection is dropped.
This would fit with the point at which my upload ALWAYS gets interrupted.
I tried it again this morning doing a null change for about 2,500
elements. It didn't lock me out permanently this time (so maybe that was
a different problem), but it did consistently drop the connection after
what looked like about 250 elements (if our server is set to 256 that
would be more of a smoking gun).
We could solve that with a retry in JOSM (was that already done - I
haven't updated by JOSM in a couple of weeks?). (Though I got a later
'precondition failed' - is this related? I deleted a way which didn't
get deleted on the server - because of the timeout? Does a request get
lost when it times out? Am I therefore losing data?)
But that's not really the same as I was seeing yesterday and the two
previous occasions (though if I didn't lose the connection, I might not
be getting into this situation).
I tried again and I *did* get locked out the second time, but only for
about 10 minutes this time (was 25 last night). Slightly surprisingly
during this time I *could* get access from another machine on my
intranet, so it must be either something on my PC or something in the
router that knows about my machine specifically, and *not* my ISP or the
server. There's nothing I can look at (log etc) or set in my router that
would affect this (it's a Belkin Wireless G Plus MIMO, FWIW). It doesn't
appear to be Windows Firewall, or Windows Defender and I'm not running
anything else that would be intercepting traffic AFAIK. I'm stumped.
BTW, I can't successfully ping www.openstreetmap.org at all at any time
or from any network I have access to.
