Hi all,
I have a job on Jenkins 1.500 that runs on a slave and produces 5 tiny
files which are then copied as artifacts.
The slave is connected via the SSH plugin.
The files are of a total size less than 1 Mb and the job seems stuck in
Copying Artifacts for hours...
The same job was last run around November using ~ Jenkins 1,485 (not sure
if this was the exact version but should be close enough)
Interestingly the same job copies artifacts at the beginning from another
job of size ~1Gb and it takes less than 30seconds to complete.
What looks worrying is that a couple of threads including main and channel
seem to be in a waiting state.
Any ideas ?
Here is the threadDump:
