i had a chance to run the sensor with the Sparkfun library for 50 hours continuously and it remains very stable and accurate. If i then switch back to the Adafruit library, i get the same high altitude mentioned above. Please try to duplicate the problem with your example code. thanks.

hello! please try with the most recent code here: https://github.com/adafruit/Adafruit_MPL3115A2_Library

I tested for a long time on an adafruit Metro and an adafruit Meto M0 and ran into no issues.

Thank you for testing it. I rebuilt my sketch using the SF library but let me test it on something other than the Arduino Uno. doubt it but that could be the issue.

yeh we think it was some delays and the way we were querying the sensor (now fixed)
