• Hi Gordon,

    Thank you for your fast response.

    I've checked using the process.memory().usage. Finally I found that there were a pin that was not pulled up or down and it was used in a setWatch. This pin was also near to another pin used for I2C communication, so it receive a lot of electrilcal noise. The state of the pin was changing extremly fast and uncontrollable, filling the buffer. After removing the setWatch the error has disapeared.

    Thank you for all.
