If you encounter similar problems on recent versions of Jenkins and up to date slave.jar on agents, please file a new bug instead of reopening this one. It's too old to be useful. Provide as much information about your configuration as possible.

We have the same situation. Build jobs which uses the clone workspace let the slaves die with the above message. All other builds work fine and do not make any trouble.

We have a setup with three jobs:

1. clean deploy -DskipTests=true
2. test
3. site site:deploy

here is the complete log of the test-build

between 'Baue auf Slave' and the error is a time frame of about one minute.

the compile-job was executed on the same slave.

This is a mere blocker!

We tried with reducing the load (only one build running), changing the jdk from 1.6.0_16 to 1.6.0_20 but nothing helped.

I looked a little bit further:

The first job runs fine an creates a workspace.zip on the master - not on the slave

It seems that the following job has problems to access this file (even if it is running on the same slave).

After a minute a timeout of hudson occurs and kills the slave.

On our testing system it is working - but this is a build which is very small. The same build on production also works.

Perhaps there is a problem with the size of the workspace.zip (e.g. buffering)?

testing (working): 6404 bytes
real build (problem): 38494759 bytes

Is there any progress on this problem?

I assume that this is a problem in hudson core.

We tried to simulate the clone workspace by doing a wget on the 'Download all files as a zip' link and unpack them. The same error occured.

I assume that the problem is on the master closing the connection and not on the client-side.

Seeing the same thing here.

I have an upstream job, "MyCode-upstream," using the Clone Workspace SCM Plug-in to publish files, and a downstream job, "MyCode-downstream," using Clone Workspace SCM Plug-in to pull the upstream job's published files. The downstream job fails with hudson.remoting.RequestAbortedException (full Console log below).

I've also set up a pair of test jobs, "foo-upstream" and "foo-downstream", which use the Clone Workspace SCM Plug-in just like the "MyCode" jobs do... and they work EVERY TIME! Also, after running the "foo" jobs the "MyCode-downstream" job starts working - WTH???

One noticeable difference is the size of the files that the Clone Workspace SCM Plug-in publishes: ~3KB for the "foo-upstream" job, and ~22MB for the "MyCode-upstream" job.

Console log from the slave machine running the "MyCode-upstream" (SCM Client) build:

I did some more testing with my previously mentioned "foo" jobs - I varied the size of the content packaged by the Clone Workspace plugin and noticed that when the content grew much larger than just 64KB (though even that number was not consistent) the downstream jobs (running on slaves) would fail. NOTE: the slave agents were restarted before kicking off the upstream job.

An example of the steps I used:

1. configure "foo-upstream" to only have a 256KB text file, which the Clone Workspace plugin packages up
2. restart slave (where "foo-downstream" is tied to run)
3. run "foo-upstream"
   • kicks off "foo-downstream" which fails with the above error
4. change "foo-upstream" to only have a 32K text file.
5. restart slave (where "foo-downstream" is tied to run)
6. run "foo-upstream"
   • kicks off "foo-downstream" which WORKS!
7. change "foo-upstream" back to have a 256KB text file (like in step 1)
   • DO NOT restart the slave
8. run "foo-upstream"
   • kicks off "foo-downstream" which WORKS!

This is most bizarre and I'm at a loss for what to try next. Any ideas?

i just got the same stacktrace in the warnings parser with hudson 1.380 on a win32 slave (running in virtual box), master is linux 64bit.
