> Our ingestion tasks run on MM nodes - I had a look, and it seems to take
about 8-10 seconds to go from JVM start to reading Kafka.
Great! In my case, I looked at the point when the httpServer was started by
the task so that it can respond to `/status` calls from overlord.
The log line I searched was something like `Started
ServerConnector@6e475994{HTTP/1.1, (http/1.1)}{0.0.0.0:8102}` which happens
roughly at the 4th second after the tasks start. And runNotice at the overlord
gets stuck

for that duration until task can respond to the `/status` call. This is my
observation. Does it make sense?
