Had time to look at this again today and found the issue. Patch installation upgraded Apache CXF components but left all old libraries lying around. Fixed by moving the old cxf*3.3.4 libraries and restarting the services.

Code: Select all

find /opt/zimbra/ -iname "*cxf*"
./lib/jars/cxf-core-3.5.1.jar
./lib/jars/cxf-core-3.3.4.jar
./jetty_base/webapps/service/WEB-INF/classes/cxf.xml
./jetty_base/webapps/service/WEB-INF/lib/cxf-rt-frontend-simple-3.3.4.jar

find /opt/zimbra/ -iname "*cxf*3.3.4*" -print0 | xargs -0 -r -I {} mv {} /root/2020_06_26_Zimbra_cxf_3_3_4_backup/

su - zimbra -c "zmcontrol restart"
As there also had been some posts regarding the Java mailboxd options that are to be applied after patching, the following options are the one's that I'm currently using successfully

Code: Select all

mailboxd_java_options = -server -Dhttps.protocols=TLSv1.2 -Djdk.tls.client.protocols=TLSv1.2 -Djava.awt.headless=true -Dsun.net.inetaddr.ttl= -Dorg.apache.jasper.compiler.disablejsr199=true -XX:+UseG1GC -XX:SoftRefLRUPolicyMSPerMB=1 -XX:+UnlockExperimentalVMOptions -XX:G1NewSizePercent=15 -XX:G1MaxNewSizePercent=45 -XX:-OmitStackTraceInFastThrow -verbose:gc -Xlog:gc*=info,safepoint=info:file=/opt/zimbra/log/gc.log:time:filecount=20,filesize=10m -Djava.security.egd=file:/dev/./urandom --add-opens java.base/java.lang=ALL-UNNAMED -Djava.net.preferIPv4Stack=true
