Florian Ramillien added a comment - 2018-10-24 16:23 The result is the same, yes. But I don't think the cause was the same, in our case connection with agent is working unless some specific combinaison of components: A long build with a simple task (ping during 20mn) is working A shorter build (10mn) with hudge log generated by "bat" step, fail (see previous comment). Removing "timestamps" step from pipeline fix this issue Reverting from "push" to "pull" logs in "durable-task" fix this issue too. In our case, something occurs at the end of the job between master and slave, and master never receive the "OK" result from slave (nor the full logs). And after 9mn of inactivity build fail and agent is disconnected. It's always reproduced with hudge logs, but maybe logs size is just a factor triggering another hidden synchro/lock problem. For now "USE_WATCHING=false" is set in our Jenkins master and is an acceptable solution for us.

Ljubisa Punosevac added a comment - 2019-10-11 11:45 - edited Hi,  Unfortunately, this problem still prevails on Jenkins ver. 2.190.1 and timestamper version 1.10 . I tried also older versions of this plugin for which has been written here to work, but again with the same results. Also, the following option has been set on Jenkins master as JVM parameter, but again with the same outcome: -Dorg.jenkinsci.plugins.workflow.steps.durable_task.DurableTaskStep.USE_WATCHING= false All our jobs are pipelines and timestamps appear only in a few places. Most of the time they are gone. [Pipeline] configFileProvider [2019-10-11T11:22:10.289Z] provisioning config files...

Best, Ljubisa.  

Jesse Glick added a comment - 2019-10-11 20:04 Ljubisa Punosevac it is hard to know offhand what your issue is. If you are consistently missing timestamps, it would be better to file a fresh bug with complete, self-contained steps to reproduce your problem from scratch , and link it to this one.
