TL-MR3020 crashed again: Cannot allocate memory

Postby ironedge » Tue Apr 07, 2015 11:48 am

Hi Boris,

My TL-MR3020 crashed again, so it looks like there may be another Memory leak left. I did not have any internet connection drop so this cannot be the reason as assumed the last time (data buffer filling up). In addition, I loaded the new Firmware after the last crash as you advised.

My guess would be that the Memory leak origins from the Virtual sensor calculations as I'm doing this regularly and heavily. The virtual sensor calculates the sunshine duration. Find here the logfile extract:

logger (06.04.2015 15:24:36): cannot open pipe "gzip >/var/run/meteohub/inetupload.z": Cannot allocate Memory

I had the following Client HW/SW Setup at the time of the Crash:

Client SW: 2.4 (FW 1.1, Build 5450)
Client HW: 265 BogoMIPS, TL-MR3020

Now after the reboot it's 2.5 (FW 1.1, Build 6239).

I have the TL-MR3020 with the Meteostick (no Meteobridge, etc.), collecting data from a Davis VP2.

Any help would be greatly appreciated. The Meteoplug solution is awesome and runs great but those crashes due to a Memory leak every 2-3 months are a bit painful. If you find the origin of it and could fix it, that would be perfect!

Many thanks in advance for your help.
