Ahhh. The parallel processing in << common-src/bsdtcp-security.c,
function runbsdtcp >>
*ALSO* does not call asynchronously, and is ALSO giving me a 3 minute TCP
wait
if the node is actually down.Both bits of code have comments saying they
are calling
asynchronously, but neither one is doing so yet.
I understand — it’s an effort to code that! I’ve only gotten as far as
realizing that both
bsdtcp and krb5 go through this same spot in the code. <<
common-src/util.c, function connect_port >>
I *had* already realized that both bsdtcp and krb5 clients were giving me
3 minute TCP waits
(later, times the “connect-tries” parameter in my config, which defaults to
3). I did try setting that to 1
and lost all my other (up) clients anyway.It seems to be the first wait
that bothers everybody else.
So — TCP nodes (which means bsdtcp and krb5 and maybe others, but not bsd
)
have wait times which defaults to 3 minutes 9 seconds
times “connect-tries” if a node is offline.
If I didn’t have any bsd clients (udp connections) would this not be
bothering me?
Do you other people with only bsdtcp and/or krb5 clients have no
problems if a node is
offline?
(If so, then I’ll push to upgrade those older clients, instead of
trying to re-write the code!)
