Here is also crashing. Usually takes hours or a day, I tough the problem was related to the example of octoWS2812, but seeing that other people has problems with other sketches makes me think the problem resides in the ethernet library or maybe a power faliure? I will keep digging.
I am using Teensy 3.2 with the WIZ820io & Micro SD Card Adaptor, the WIZnet WIZ820io and the OctoWS2811 Adaptor. I'm not using DHCP.
Make sure you have a rock solid 3.3V power supply! If the voltage sags down to below 3.15V the WIZ820io seems to hang up randomly.
Updating to the latest version of the libraries seemed to help. I also found a bug in my code that it would try to read more bytes from the stream even when there was actually available, this sometimes caused a crash of the WIZ module. Attempt to read 0 bytes also causes unusual behavior.
