Description

« Hide

We have a stuck build with:

11:22:09,812 INFO - Checking step execute condition...
11:22:09,826 INFO - Step execute condition satisfied, executing...
11:22:10,737 INFO - Executing pre-execute action...

11:22:10,739 INFO - Checking out revision 'configuration:root/bla/trunk/CI/builds/native/linux-x86-32, build id:1779981' of repository 'qb-native-linux-x86-32-remote'...
11:22:10,740 INFO - Waiting for finish of dependency build (configuration: root/bla/trunk/CI/builds/native/linux-x86-32, build id: 1779981)

When I open the build with the id 1779981 it is already finished successfully some time ago.

I also attached the jstack output of agent and server

The behavior can also be reproduced. I had to kill the qb agent and then I restarted the build. And it got stuck at the exact same place.

From stack trace, the thread is transferring artifacts from server at the time checking out the dependencies. How large are the artifacts?

The artifacts have about 400 megabytes had to travel some distance. Usually that's not the problem. It seems that it works again. Maybe just a connection issue. We'll observe that and if we experience it more often I'll reach out to you.
