[zeromq-dev] Closed dealer socket may cause context termination to hang

[Frank Hartmann]

Hi,

Sorry to jump in into the middle. Has the LINGER option been fixed in
the meantime (==in the last 12 month)?

The only values which were working @4.0.0 as documented were 0 and
inf. I think for all other values the system would block for the LINGER
amount, but not send messages during that period.

https://zeromq.jira.com/browse/LIBZMQ-554

So basically the behaviour of a LINGER set to two seconds was at the
time I wrote the bug:

- do nothing for 2 seconds
- stop

I would have expected:

- send out queued  messages for 2 seconds
- stop

So clearly 0 seconds is much better if the behaviour has not been
changed...

kind regards
  Frank
