Patch PE83-1903040
------------------

Platforms: All

* Fixed database server internal deadlock condition that could in rare
  cases result in a hanging server process (#4285).

  A deadlock condition was fixed in the database server cache management
  that could result in a (partially) hanging server process.
  A thread status (dbctl list thread or thread status dumped on shutdown)
  indicates a block in the mpool subsystem.

  This was caused by a potential lock ordering problem when a cache buffer
  was reused by a concurrent connection.
