Description
On xwiki.org, we had a lot of threads blocked waiting for a lock help by no thread.
Increasing the acquire-timeout of the "templates" cache (as suggested on https://stackoverflow.com/questions/35711423/how-to-fix-unable-to-acquire-lock-after-15-seconds-errors-in-wildfly) seems to have helped a lot:
