[Solved] Upgrade 8.6.0 P13-->8.8.10 P3 works but admin console unusable and stuck at "Loading ..."

The previous installation with working admin console, etc., was Release 8.6.0_GA RHEL7_64 FOSS edition, P13. After performing an upgrade using zcs-8.8.10_GA_3039.RHEL7_64.20180928094617, the system appears to be working in all respects related to acting as a zimbra server. $ zmcontrol -v Release 8.8...

[Solved] High CPU java condition for mailboxd on Zimbra-8.6.0 (P12)

This issue was noted on zimbra 8.6.0 GA 1153, but P12 was available, so the patch was applied early in the troubleshooting process. The condition persisted after patching. The rest of the post below documents post-patch troubleshooting. $ zmcontrol -v Release 8.6.0_GA_1153.RHEL7_64_20141215151110 RH...
