[libmicrohttpd] MHD_USE_POLL trouble

[klemens]

Hi all,

I'm struggeling with MHD_USE_POLL. Starting the daemon on debian8 with

        daemon = MHD_start_daemon (     MHD_USE_INTERNAL_POLLING_THREAD 
                                                                | MHD_USE_POLL, 
...)

on port 55301 results in a process beeing permanently active, using up
1 CPU completely with only a few requests every minute, though top cmd
shows, the system is 97.5% idle, with the daemon almost permanently
active on the first line counting up time+ with the refresh rate:

%Cpu(s):  2,5 us,  0,0 sy,  0,0 ni, 97,5 id,  0,0 wa,  0,0 hi,  0,0 si
top - 13:09:00 up 1 day,  1:31,  7 users,  load average: 1,09, 1,07, 1,05
Tasks: 474 total,   2 running, 472 sleeping,   0 stopped,   0 zombie
%Cpu(s):  2,5 us,  0,0 sy,  0,0 ni, 97,5 id,  0,0 wa,  0,0 hi, 0,0 si, 0,0 st

Can anybody please help, what I misunderstand, or what I'm just doing
wrong here.

Thanks in advance, kginbg.
