I've noticed since updating to current from 4.0-current in January to
-current now that certain commands through bgpctl seem to just
hang .. (we've tried this with various snapshots every 2 weeks or so
since January) as well as trying a full build.
If I do a bgpctl reload (100+ peers per production router) and then
within a minute or so do a bgpctl show then bgpctl's output just
hangs (I've left it for nearly an hour and nothing has appeared
beyond the headers)
Hmm. That's strange. Does it work after waiting a longer time?
bgpctl show can block for some extended time (if the RDE is busy) but you
should get a result back.
Also regardless of a reload, attempting to show rib nei a.b.c.d out
also just seems to hang
bgpctl show rib nei 80.252.124.1 out
flags: * = Valid, = Selected, I = via IBGP, A = Announced
origin: i = IGP, e = EGP, ? = Incomplete
flags destination gateway lpref med aspath origin
and no more output
You're right we have a polling issue here. I'm looking into it.
In short, the RDE blocks and does not continue to process the show command
until an update or some other message was received because the current
batch of work did not queue any outgoing imsgs. The poll(2) timeout needs
to be changed to 0 in this case.
... and here is the patch to fix the issue.

That patch did not fix the issue for me(running 4.1 with -current
bgpd). There is almost no load on the box.
# time bgpctl sh rib out
snip
Takes forever, 10+ minutes. However, if I open another terminal and
type:
# bgpctl sh rib in
The sh rib out will finnish almost instantly and the rib in will
finnish in less then a second. The output of sh rib out is not what
I'd expect though. The networks I've defined in my config will be show
twice(that is true even if I'm not speeding things up with the sh rib
in).
If any patch gets sent to the list I will probably not have time to
test it before the end of the weekend.
