Memory leak in Kadabra.Supervisor

Question

Closed this issue 7 years ago · 3 comments

My application using Pigeon 1.1.0 and Kadabra 0.3.2 crashed (after 28 days uptime) with:

eheap_alloc: Cannot allocate 762886488 bytes of memory (of type "heap")

Running the erl_crash.dump through:

/usr/lib/erlang/lib/observer-2.5/priv/bin/cdv erl_crash.dump

Shows Elixir.Kadabra.Supervisor using 721 MB of memory at the time of crash. Which is 90x the next-biggest process, ssl_manager at 8 MB.

I'll take a look, probably old connections aren't getting cleaned up.

Looks like the hpack tables survive connection close. Fixed with #21, though I want to do some rework before publish.

@hpopp Wow, thanks for such a quick fix!
