      The "Session validation interval" in the Crowd2 configuration is set to 10 (minutes?). Well, the configuration form always reverts back to 2 which seems to be a bug. However, the config.xml contains the correct value of 10.

      Anyway, for some reason this value seems to be ignored completely.

          [JENKINS-16703] Too many periodic requests to Crowd server

          Arnaud Héritier added a comment -

          No progress for now. "We" need to solve JENKINS-17957 and https://github.com/jenkinsci/crowd2-plugin/pull/9 before implementing the cache change. You can use the SNAPSHOT attached to the ticket as a workaround but it will probably not compatible with the next release thus for a future upgrade you'll have to reconfigure the plugin completely

          every 5 seconds the same requests (round about 300requests)....is there really no fix?? it slows down crowd application with high cpu load

          Just install the SNAPSHOT attached to the case and configure the cache. It's all what we have nikomad

          There is sadly no active maintainer on this plugin

          Hello Arnaud,

          thx for your fix. It works like a charm. My crowd and jenkins were on very heavy load. Now it looks better

          Hi all,

          version 2.0.0-beta1 has just been released and should be available soon in the Experimental Update Center.

          Works on my machine™, but would be great if many of you could give it a try and check if it works as expected before the final release. Here's how to configure the Experimental Update Center https://jenkins.io/doc/developer/publishing/releasing-experimental-updates/
