Intro After a few months of occasional filter wheel errors, did another attempt to improve things. Retires in the filter task was improved, but this didn't help. March 2022 Here is a list of Errors/Attempt from the filter process debug code to evaluate solutions. Improving retires didn't work. Felt that the problem wasn't smokey or the RIO (working well from 2018-2021-ish). Maybe it the network?, something casching routing? Setting up a ping cron solved the errors from Mar 21-Apr05. Will leave a 5min ping cronjob to smokey-rio from the smokey PC going. Error/Tries Mar 13 - 1 / 5 Mar 14 - 3 / 18 # troublelog say "nearly every Smokey filter move sent it to an ERROR state" ??? Mar 15 - 0 / 9 Mar 16 - 0 / 6 # updated smokey to v2203 (with better retries) Mar 17 - 1 / 2 # 2 init to recover. Mar 18 - 0 / 4 Mar 19 - 0 / 2 # 1 sucessful retry. Mar 20 - 3 / 16 # ----------------------------------------------------------------- Mar 21 - 0 / 5 # ping -i 30 smokey-rio Mar 22 - 0 / 2 Mar 23 - 0 / 2 Mar 24 - 0 / 4 Mar 25 - 0 / 8 # ping -i 60 smokey-rio Mar 26 - 0 / 9 Mar 27 - 0 / 5 Mar 28 - 0 / 3 # setup a cronjob to ping every 2 minutes Mar 29-31 0 / 8 Apr 01-05 0 / 14 # setup a cronjob to ping every 5 minutes - Will conider this closed.
