問題
Confluence thread spikes randomly, and Confluence seems to grind to a halt. Thread dumps taken 1 minute apart shows the following long running thread:
com.xpandit.confluence.plugins.link.preview.rest.LinkResolver.retrieveType(LinkResolver.java:67)診断
- Take 3 external thread dumps spaced 1 minute apart, during the thread spike: Generating a Thread Dump Externally
- Analyze the thread dumps using tools such as TDA: https://java.net/projects/tda
- Look for long running threads that are in the "Runnable" state. This KB applies to you if you see threads such as the one highlighted above
原因
The Link Preview plugin for Confluence: https://marketplace.atlassian.com/plugins/com.xpandit.plugins.linkpreview-confluence
