[Twisted-Python] Incorrect "Another twistd server is running..."

When my server reboot after an unexpected power cut, supervisord tried to start a twisted app after an unexpected power cut, but it fails because "Another twistd server is running, PID 4607" 4607 is the PID of the twisted app before power cut. After I stopped and restart supervisord, everything is

Hi Gabriel had the same problem, solved it by having keepalive() called in a LoopingCall(), MySQL sitting at defaults timingwise. DB_DRIVER = "MySQLdb" USERDB_ARGS = { 'host': '', 'db': '', 'user': '', 'passwd': '', 'cp_reconnect': True } storekeeper = StoreKeeper(DB_DRIVER, **U

Regarding the original question: "how to make mysql's idle timeouts shorter so that I can debug my code?" You should be able to do that in the mysql shell: mysql> show variables like '%timeout%'; ++---+ | Variable_name | Value | +---

Instead of trying to keep the connection alive you can also just reconnect when necessary. Example code here: http://stackoverflow.com/questions/207981/how-to-enable-mysql-client-auto-re-connect-with-mysqldb/982873#982873 On Tue, Jul 21, 2009 at 2:18 PM, Clay Gerrard wrote: > Regarding the origin

Hello Werner, Thanks for your idea, I will give it a try if my current "fix" doesn't work well (reconnecting if I get a connection lost exception and re-running the query). Gabriel Werner Thie wrote: > Hi Gabriel > > had the same problem, solved it by having keepalive() called in a > LoopingC

Hello Clay, thanks! It will help me debug my code by setting a low timout. Gabriel Clay Gerrard wrote: > Regarding the original question: > "how to make mysql's idle timeouts shorter so that I can debug my code?" > > You should be able to do that in the mysql shell: > mysql> show variables like

Hello Garret, yes, I finally did did something like that, I am currently testing the code. Thanks, Gabriel Garret Heaton wrote: > Instead of trying to keep the connection alive you can also just > reconnect when necessary. Example code here: > http://stackoverflow.com/questions/207981/how-to-e
