8 years ago It looks like /opt/vc/bin/vcgencmd is unavailable at the time it was required, while querying measure_clock arm, which is the first vcgencmd-related query whenever bcmstat.sh wakes up.
Were you upgrading your firmware (using either apt-get or rpi-update) while running bcmstat.sh, as this might conceivably cause vcgencmd to be replaced/overwritten leaving it momentarily unavailable to processes such as bcmstat.sh.
bcmstat crashed the other day with the following output:
Traceback (most recent call last): File "/home/daco/bin/bcmstat.sh", line 1433, in

I have never seen a crash in bcmstat before. Do you think the problem is with my side or the bcmstat side?
Thanks,
