CDH5.7.1 Impala Statestore Memory Leak

[#1]

Hi, Are there any memory leaks in Statestore CDH5.7.1? The memory used by statestore rised from 1G to 20G in a month. Thank you for your time on this problem.

What does the /topics URL show in terms of the size of each topic
registered with the statestore?

I've restarted the statestore in 4 days ago. The statestore's memory is rising, and VIRT is 155G.
