I am using the Vsphere Cloud plugin to spin Jenkins agents (slaves) on demand in new virtual machines using linked clones and keep-until-idle retention strategy. In the Jenkins instance there are a mix of "static virtual machines" Jenkins agents and Jenkins agents on demand

The plugin works correctly until a certain time or maybe limited number of agents created. Approximately after +-70 builds or 12 hours the virtual machines are created correctly, connected to Jenkins but they are shutdown before the build is allocated in the agent or virtual machine.

The following is a piece of log of the main Jenkins.log file when this situation occurs, this is happening over and over.

If we take a look to the log of the agent in the Jenkins UI the following can be seen

HTTP ERROR 404


Problem accessing /computer/ess-lin_8hbmdsbdw82ekvakhf1667bk/logText/progressiveHtml. Reason:

This situation is fixed when I set back to 0 the instance cap limit (for some reason instead of 0 the Jenkins UI shows a number of 2147483647 instead of 0 and the plugin starts immediately working fine again.

When I set it to 0, the following error appears in the main Jenkins.log file:

Is there something I can do to fix this behaviour ?

Thank you in advance
