Error description
Admin Console: Rebuilding Hierarchy Tree Cache taking forever. Duration of rebuild is taking too long (50-100 HOURS). Development has done some digging, and found that the rebuild cache is being done across all servers in an environment when it should only be done on the process server (running the Platform Maintenance Agent) and the rest of the servers should pull from the database cache. When there are 4 servers in the environment, when the process server is done rebuilding the cache, it puts an event into the heartbeat queue to tell the others to flush their cache, but the command executed on the other servers is a rebuild, not flush.
Local fix
No.
Problem summary
After the Platform Maintenance Agent was done rebuilding the Hierarchy trees, it sent an event to other servers to clean and rebuild the trees as well. On a multi-application server environment, this could cause blocking as each server was competing to write to the database.
Problem conclusion
Made a change where only the cache is flushed on other servers when the Platform Maintenance Agent has completed its work. Before the change, each of the servers would receive a notification to rebuilt the whole cache, rather than just flushing it. This is targeted for the 3.4.2 release as well as targeted for the 3.4.1.2 fix pack.
Temporary fix
