Description
We have very similar issue to UNDERTOW-1486. Basically we have same symptoms.
Oldgen is slowly increasing until our application fails on OOM. This started to happen after migration from WF13 to WF15 (WF 16 has same issue).
Memory is allocated in one HttpOpenListener which seems to keep references to HttpConections. Amount keeps growing until memory is depleted.
Difference is that same behavior happens for WF16 (Undertow 2.0.19.Final) which should have fixed version of Undertow included. Also we don't use ALPN ( I haven't seen it during debugging) so this is quite important difference as bug has been found there. Downgrading to Undertow 2.0.18.Final didn't help as well so this bug probably just looks similar.
I have attached leak report from MAT
