-------------------------

             Summary: System under memory pressure (414.25% of limit used). However, there are no ops currently runnable which would free memory 
                 Key: KUDU-3241
                 URL: https://issues.apache.org/jira/browse/KUDU-3241
             Project: Kudu
          Issue Type: Task
          Components: tserver
    Affects Versions: 1.10.0
         Environment: centos 7.7
            Reporter: sun


hi  everybody，
When I use kudu to store data in the production environment, I find that the memory of kudu tserver is not limited, or is constantly consuming the memory of the operating system, and I have not found an effective patch to fix this problem。

One of my tserver, totally 256G memory, gflags: 
-memory_limit_hard_bytes= 26843545600 (25G)  -memory_limit_soft_percentage=85 -memory_pressure_percentage=80

but in "top" and webui of tserver  ,i find memory is used over 25G ,and then kill tserver because of OOM.

could anybody give me some tips? thanks in advance.
