Hello Zaker,
Thanks for reaching out!
I tested your code and, as expected, it didn't fail. I'd probably have to wait a long time before being able to see the issue. I'm not sure how you could handle this error from Python, nevertheless, if the process is stopped I might have an idea of how to solve this problem.
You can use the script originally mentioned in
https://communities.intel.com/message/445830# 445830
https://communities.intel.com/message/445830# 445830 in order to monitor a running process and restart it whenever it stops. The code would look like this:
# !/bin/bash
check_process() {
echo "$ts: checking $1"
[ "$1" = "" ] && return 0
[ `pgrep -n $1` ] && return 1 || return 0
}
while [ 1 ]; do
# timestamp
ts=`date +%T`
echo "$ts: begin checking..."
check_process "python
lcd.py"
[ $? -eq 0 ] && echo "$ts: not running, restarting..." && `python
lcd.py`
sleep 5
done
***You'll need to install procps, procps-dbg, procps-dev and procps-doc in order to use pgrep, this packages can be downloaded from the official repo.
If this solution doesn't help you, I'd suggest you to contact the developers of mraa directly (
https://github.com/intel-iot-devkit/mraa/issues) and report them the issue you are facing in order to see if they can provide you a more accurate response.
I hope this information helps you,
Pedro M.
