Some buffering issue freeze arduino mega

[nahornyj]

Arduino mega stop working after 6 hour of receiving artnet trames. the only solution I have in mind is to reset the arduino each 5h to make it work again. Is there a more elegant way to prevent freezing? Is there some memory overloading involved? my setup : artnet is send from computer to the arduino through ethernet shield then arduino act on I2C relays. I use 2 libraries : your artnet library and the library from grove to control the i2c relay (https://wiki.seeedstudio.com/Grove-4-Channel_SPDT_Relay/). The library use Wire to talk to I2C devices. I'm trying to figure where is the issue. Do you try to make your receive exemple working for more than 5hours?
