What Tomcat version are you using? Has there been any change in Tomcat version in the same time frame? If so, please provide exact version information. Please provide the AJP connector configuration from Tomcat's server.xml > [Wed Mar 22 15:08:46.746 2023] [10780:14112] [error] > ajp_connection_tcp_get_message::jk_ajp_common.c (1408): (tomcat01) wrong > message size 18441 8192 from ::1:8009 This suggests that Tomcat is configured with a different maximum AJP message size than IIS. Please provide your workers.properties file.
