[PD] metro slow down + audio drop-outs

[Nicola Pandini]

Hi list,
I have a patch that acts as MIDI master, that sends MTC and other data 
via udpsend to 4 udp ports.
It happens that sometime the patch's audio metronome begin to slow down 
for a bunch of seconds. I also hear cracklings in metronome sound (the 
metronome patch is based on a simple [metro] object).

I don't see any xrun, so I'm starting to think it's a problem of the 
patch. Maybe the buffer of udpsend? Because it seems to happen when I'm 
sending more data than usual (not everytime, though).
Can you give me some hints? I'm using pd-extended on Debian Jessie.

     Thanks
