Intermittent errors: [E][WiFiUdp.cpp:183] endPacket(): could not send data: 12 #165

I've been working on a project to connect a RF controlled ceiling fan/light to my Alexa.

I have been struggling with getting intermittent errors [E][WiFiUdp.cpp:183] endPacket(): could not send data: 12.

I've set DEBUG_FAUXMO_VERBOSE_UDP to get more information.

Here is a copy+paste from the Terminal. `[FAUXMO] UDP packet received M-SEARCH * HTTP/1.1

Error 12 is ENOMEM

I have three components that are using UDP. NTPClient which I had wrapped explicit logging around the endPacket() call to leave some fingerprint. It has not corresponded with any issues.

The other is Syslog. I actually swapped the Syslog implementation as this was a lot more complex to modify. I'm not able to correlate the issue coming up with any errors like I can with fauxmoESP.

I have logging of basic memory information: Every 5 minutes. [loop] Health Check: Free Heap:[255088] Max Alloc[113792]
