From build 5561 onwards, including 6.0 beta, IntelliJ uses 100% of the CPU shortly after loading a project. This did not happen with earlier builds. I see that someone else also has this problem and has raised a JIRA (IDEA-8435) and has also included CPU snapshots. Like me, they are also running on Linux. I tried all the usual things - removing plugins, clearing caches etc but the problem is still there.
How widespread is this problem? Has anyone else seen this running on Windows or Mac? I assume that the CPU snapshots already attached to the JIRA are sufficient to help fix the problem?
