03/03/2020, 2:20 PMHi! I'm all of a sudden getting some failed flows/tasks due to Zombie Killer Process marking tasks as failed after they have completed successfully. Any suggestions?

03/03/2020, 2:30 PMHi @Cab Maddux, sorry you're running into this issue-- looking into it on our end. In the meantime, are heartbeats enabled or disabled for your flow?

03/03/2020, 2:34 PMHeartbeats should be enabled, we haven't disabled them

03/03/2020, 2:42 PMOkay, solid. I'm not 100% sure what prompted the Zombie on your end, but disabling heartbeats for your flow should prevent this problem moving forward.
I'll keep looking into this, and let me know if you have any additional questions!

03/03/2020, 2:44 PMOK sounds good, seems like a flaky problem, just reran the flow and succeeded so I'll keep an eye on it and we'll disable heartbeats fi continues

03/03/2020, 2:48 PMNVM not flaky, happened on that run as well, we'll disable heartbeat for this flow for now
