About the ssh cmd 'gerrit show-queue'.

[Z]

Hi

    1. Lots of the 'Index-Interactive' status in 'gerrit show-queue' like the attached file which cause heavy load in server and then gerritUI hang.

    2. gerrit version : 2.13.7

    3. I do not know why, nothing exception in errorlog and many  '/gerrit/changes/?q=is:open+owner:self&q=is:open+reviewer:self+-owner:self+-star:ignore&q=is:closed+(owner:self+OR+reviewer:self)+-age:4w+limit:10&O=881' in httplog

    4. The log from jstack

The screenshot shows 8 tasks in the Index-Interactive queue, maybe you
can try reducing the number of threads used for indexing? Maybe you can
reduce the number of threads via the Gerrit configuration settings
index.threads (default 1 + number of CPUs / 2) and index.batchThreads
(default number of CPUs).
