Description

In the build https://asterix-jenkins.ics.uci.edu/job/asterix-gerrit-asterix-app/3222/console

The recycling of the memory component of the LSM R-Tree deadlocked because it pinned a free page and tried to get a write latch on it.

However, a read latch that was acquired at some point was not released.
