Mysterious Resets

[DrewJaworskiRIS]

I have wasted an embarrassingly large number of hours trying to track this down. My Arduino will reset itself (or sometimes just freeze up) when sending a TCP packet using this library. Everything works fine if all I send is UDP packets to Exosite. This problem seems to have crept up in the last 6 months or so. I understand I am probably in a minority here, so I am willing to accept that the problem might lie in my hardware or some forgotten modification to some other library.

Nonetheless, if you want to dig into this with me, I will compile more information to send. Meanwhile, can someone else compile and test some examples with the latest Arduino IDE (I am using 1.6.13 right now; the release notes indicate that the newer versions are mostly just IDE updates). Please help me confirm it isn't something to do with a regression outside of my domain, which no one else has happened to notice yet.

Meanwhile, I'll just have to start using UDP packet only and stop using this library, unfortunately. I'd rather have my products not know whether data is successfully being sent to the server, instead of crashing/resetting randomly.
