[JIRA] [build-timeout] (JENKINS-23012) Build-timeout plugin causes builds to slow

[de...@ikedam.jp (JIRA)]

ikedam commented on JENKINS-23012 Build-timeout plugin causes builds to slow I agree that it's risky to install testing versions to the production environmtnt. I'm not so sure what the root cause is and how to fix that. I'll try to reproduce it in my local enviroment. Please let me know followings: OS of the master node and slave nodes. Outline of your build process. For example, running maven, running gcc, or running other native process. I think whether builds are performed in Java or native processes can affect this problem. How much log outputs? I think the size of whole log and the time builds take will be helpful. I think much log outputs may trigger the problem. Can you see what process gets slow in builds? If building processes outputs timestamps, please compare them before and after downgrading build-timeout plugin. If you installed Timestampler plugin, please compare timestamps in console outputs. Timestamps logged with timestampler-plugin may differ from the activity of the building process as they can be buffered and delayed. If you don't have timestamper-plugin installed, you'd better not install that as that plugin also captures log output and may cause the same problem. I think there are following possible causes to slow builds: Native processes lauched in builds get slow. Like processes launched with "Execute shell". I don't think Jenkins cannot affect native processes as they should be completely separated by OS. But slowed log output can flood output buffers of processes and may cause the processes hold for a while. Jenkins takes much time to proceed build steps. In this case, native processes don't get slow. Jenkins takes much time to start and stop builds. This can be caused by synchronized.
