ERROR - Packet size is too large ?

[stevieosaurus]

Soon after upgrading to OLS v1.8.4 it works for a while, but in a few hours client sees "The connection has timed out" while the error log displays:

ERROR [2912] [123.456.789.123:59764:HTTP2-1#mywebsite.com] Packet size is too large - 16712

What might be causing this?

The settings look alright. And I don't see there are any changes regarding the package size in OLS v1.8.4. If you can reproduce it in v1.8.4, please submit a support request to support@litespeedtech.com with this forum post link appended.
