--- Comment #1 from Mark Thomas <ma...@apache.org> ---
I suspect this is triggered by local port re-use. Possible scenarios for that
are described in bug 65776.

I suspect what you really need is an update to Tomcat 9.0.59 or later.

It might be possible to reduce the frequency via configuration (e.g. disable
HTTP keep-alive) but those changes may cone with performance impacts.

The users list is the place to discuss possible workarounds if a Tomcat upgrade
is not possible.
