We had an application with an excess of 128 sockets, which was failing with libmosuitto due to the use of select. Direct conversion to poll solved the issue.

Is there any timeline for getting a poll patch in the mosquitto client library. This is causing client failures for our customers. I posted this pull request more than 8 months ago, and nothing.

We are facing the same issue and would be glad if select is replaced by poll. Dear maintainers, what is missing to complete this PR and have it merged in master ?

Hi @skolodzieski. Thanks a lot for your patch!! :) Would you mind rebasing it against master to ease testing?
