Handshake Failed errors repeatedly on apache2

Getting multiple errors in the log on apache2.4.18 using I believe GnuTLS/3.4.9 (pulled using 'strings' from so file)

[Thu Apr 19 08:08:35.015454 2018] [gnutls:warn] [pid 28918] (103)Software caused connection abort: [client 100.100.100.100:64811] cleanup_gnutls_session: connection pool cleanup in progress but TLS session hasn't been terminated, trying to close

These types of errors showing up on/after specific client requests Multiple errors of type: [Thu Apr 19 08:28:35.665017 2018] [gnutls:error] [pid 28360] [client 100.100.100.100:50609] GnuTLS: Handshake Failed. Hit Maximum Attempts

NOTE: I did a google search and saw a number of mod_proxy related problems producing the second error. We do not have mod_proxy enabled.
