I have ubuntu based OS (xillinux) installed on my zynq 7010 based microzed board (commercial version) and having certain scripts running on them outdoors. I have 10 such systems outdoors. But only on two particular systems, whenever I login to these system, the response from the terminal is very sluggish and CPU itself seems to be running slow. After I reboot the system, then it would start running normally, and then again after a few hours, shows up the same behavior. What could be the possible reasons for this ?
Some process is utilizing maximum CPU resources ?
Or the 8GB SD card quality isnt good (Currently using the SD card that came with the microzed kit) ? What SD card is recommended to be used if so ?
What else could be the issue ? Temperature (Currently the microzed sits on my custom designed PCB which is usually at a temperature of 30-35 C based on the temperature sensor I have on board) ?
