quota plugin can not startup and the gerrit server is no response

[Yingchun Li]

Hi,

    After building and installing the quota plugin, there is error in error_log:

[2025-12-23T17:01:17.911+08:00] [SSH-Interactive-Worker-25] ERROR com.google.gerrit.server.git.WorkQueue : WorkQueue thread SSH-Interactive-Worker-25 threw exception

Then the gerrit server became unresponsive, even the 

ssh -p admin@xxx gerrit show-connections 

hangs.

    Since there is no ready package on gerrit 3.12.3, so I built the quota myself.

and my gerrit version is 3.12.3 and jdk is 21.

Br,

Yingchun

Did you try building the plugin intree or standalone ?

I built the plugin with intree. 

Maybe gerrit version doesn't match is the problem, the gerrit is latest master,

and plugin is also latest master, but I installed the plugin to  gerrit 12.3.

I have downloaded the 12.3 plugin in 

https://gerrit-ci.gerritforge.com/plugin-manager/

Now it works. Thanks.

I have updated the quota.config on All-Projects, but it seems I still need to restart

the Gerrit server for the changes to take effect. Is that correct?

Br,

Yingchun

Restart the quota plugin or the Gerrit server
