Title: Message Title

Thomas de Grenier de Latour created an issue   Jenkins / JENKINS-30934 Changing crontab settings blocks "configSubmit" for 3x60 seconds Issue Type: Bug Assignee: Lucie Votypkova Components: disk-usage-plugin Created: 13/Oct/15 9:11 PM Priority: Major Reporter: Thomas de Grenier de Latour With recent disk-usage plugin (0.26+), changing the crontab expressions in the global settings will block Jenkins configuration for (up to) 180 seconds (when the 3 crontab settings are modified at once). Taking several thread-dumps when it happens shows, successively, the following three stacks: "Handling POST /jenkins/configSubmit from 127.0.0.1 : RequestHandlerThread[#14]" daemon prio=10 tid=0x00007f2c4820d000 nid=0x3311 waiting on condition [0x00007f2c2e7dd000] java.lang.Thread.State: TIMED_WAITING (sleeping) at java.lang.Thread.sleep(Native Method) at hudson.plugins.disk_usage.DiskUsageCalculation.reschedule(DiskUsageCalculation.java:101) at hudson.plugins.disk_usage.DiskUsageProjectActionFactory$DescriptorImpl.configureBuildsCalculation(DiskUsageProjectActionFactory.java:359) at hudson.plugins.disk_usage.DiskUsageProjectActionFactory$DescriptorImpl.configure(DiskUsageProjectActionFactory.java:293) at jenkins.model.Jenkins.configureDescriptor(Jenkins.java:2899) at jenkins.model.Jenkins.doConfigSubmit(Jenkins.java:2862) ...

The offending commit is this one, which introduces a Thread.sleep(60000) in DiskUsageCalculation.reschedule(): https://github.com/jenkinsci/disk-usage-plugin/commit/9ec92f4887032f3dadbe52f91a803b638fe7721e I don't understand (at all) the purpose of this sleep calls (is it some testing/debugging code which should have been removed before commit?), thus I'm not able to submit a PR. Thanks for having a look at this, Thomas.
