Subject [jira] [Created] (PHOENIX-4225) Using Google cache may lead to lock up on RS side.

Sergey Soldatov created PHOENIX-4225:

             Summary: Using Google cache may lead to lock up on RS side. 
                 Key: PHOENIX-4225
             Project: Phoenix
          Issue Type: Bug
            Reporter: Sergey Soldatov
            Assignee: Sergey Soldatov
             Fix For: 4.12.0

On the server side we are using google cache with life time bounds. This is integrated with
GlobalMemoryManager which is used for almost all tasks that requires memory allocation. The
problem is that when the cache member get removed, it doesn't send remove notification until
next write/get operation happen. But in some cases once the large cache was removed (but memory
manager doesn't know that since it relies on the notification), we try to resend it and memory
manager get stuck waiting for free space, blocking all other operations with the memory manager.
