Does 'logread | grep ERROR' reveal any older errors?
For some reason the present ewma passed to the function 'ewma_iteration' is not set - see this line:
You are using 'tsping' right? If so, this crash is caused by one of the four 'ewma_iteration' calls inside parse_tsping():
Otherwise it is caused by one of the four corresponding 'ewma_iteration' calls inside parse_fping() or parse_ping().
Please can you add this log_msg line before the read here:
log_msg "DEBUG" "${command[@]:1}"
read -r timestamp reflector seq _ _ _ _ _ dl_owd_ms ul_owd_ms checksum <<< "${command[@]:1}"And please can you add log_msg lines before the 'ewma_iteration' calls as follows:
log_msg "DEBUG" "reflector is ${reflector}; ewma_iteration ${dl_owd_us} ${dl_alpha} dl_owd_baselines_us[${reflector}]"
ewma_iteration "${dl_owd_us}" "${dl_alpha}" "dl_owd_baselines_us[${reflector}]"
log_msg "DEBUG" "reflector is ${reflector}; ewma_iteration ${ul_owd_us} ${ul_alpha} ul_owd_baselines_us[${reflector}]"
ewma_iteration "${ul_owd_us}" "${ul_alpha}" "ul_owd_baselines_us[${reflector}]"and
log_msg "DEBUG" "reflector is ${reflector}; ewma_iteration ${dl_owd_delta_us} ${alpha_delta_ewma} dl_owd_delta_ewmas_us[${reflector}]"
ewma_iteration "${dl_owd_delta_us}" "${alpha_delta_ewma}" "dl_owd_delta_ewmas_us[${reflector}]"
log_msg "DEBUG" "reflector is ${reflector}; ${ul_owd_delta_us} ${alpha_delta_ewma} ul_owd_delta_ewmas_us[${reflector}]"
ewma_iteration "${ul_owd_delta_us}" "${alpha_delta_ewma}" "ul_owd_delta_ewmas_us[${reflector}]"And verify that these are indeed getting properly printed in the log file? If you could post a snippet log sample below to verify that would be great.
Then we need to wait for the crash to reoccur and hopefully the log lines will reveal the cause.
Also, can you please upload your config file?

Hey Lynx,
I updated to the latest commit c4f196a and had a couple of crashes since. Attached is the last few lines of the log. Near the end, the log lists
ERROR; /root/cake-autorate/cake-autorate.sh: line 1549: ewma: unbound variable. But maybe something else is going on since there are a lot ofDATAlines near the top of the attached log, then noDATAlines for the rest.
