Hi guys,
recently switched to percona 5.5 and started having “too many connections” exceptions
i noticed that exceptions started popping up on the very first slave we pushed into the pool so it seems like after redeploy rails does not kill old connections to mysql
anyone had such problem before?
i guess options are to:
-
drop inactive connections on mysql side
-
handle deploy shutdowns better
-
stop using persistent connections
does this even make sense?
