I´ve got a big problem with my datalogger (Arduino Ethernet, included RTC 1307. After about 4-6 hours the datalogger freeze. I assumed that it´s when the Arduino are writing to the SD card.
Can everyone tell me what´s wrong?? (I´ve got about 188 Byte of ram free, all the time, when the datalogger are running.)
The Arduino code is included in this post.
