>             Project: Qpid Proton
>          Issue Type: Improvement
>          Components: proton-c
>    Affects Versions: proton-c-0.18.0
>         Environment: Linux environments with epoll support
>            Reporter: Clifford Jansen
>            Assignee: Clifford Jansen
>            Priority: Major
>
> The epoll proactor allocates a timerfd per connection.  This is a convenience 
> for the initial implementation and may surprise some applications running 
> into system limits on file descriptors twice as fast as expected.
> The timer is used for heartbeats.  It should be possible to write a 
> per-proactor heartbeat timer that is shared among the connections
