Hi #brumms, it does sound like some kind of timeout. However, 5 or 10 minutes doesn't actually sound that long - I've seen jobs that fetch for 20 or 30 minutes on very large streams.

One thing to consider is if there is any software on your network that might be cutting the TCP network connection (like a firewall or other network utility) between Jenkins and the Dimensions CM server. This seems a possible explanation given the abrupt 'Connection reset' message you are seeing.

If you follow the instructions at https://github.com/jenkinsci/dimensionsscm-plugin/blob/master/docs/logging.md (clear the log before a failed build, run a failing build, then copy-and-paste the log contents here) then there may be additional information in the diagnostic logs that helps understand what's going on.

If we can't get anywhere with it, then there is an option used when uploading artifacts to force the use of *dmcli.exe* instead of the Java API, which I could extend to apply to downloads as well - although of course it's likely dmcli will be affected the same way as the Java API if this is due to some network hardware cutting the network connections. You could also try setting up a Jenkins agent, which would use that option (to use *dmcli.exe* for download) by default

Thank you for the tips dconneely , I've added the log you suggested and will keep an eye. The issue is sporadic so I never know when it will happen, it never occurs a second time in a row either, it always works when run it again. I'll update you when I have log information and check into the network connections as well.

Hi dconneely, the build finally had a failure with this same error. Here is the log information I grabbed from it. Please let me know if you see anything that stands out causing this issue. Thank you!

brumms, the only odd thing in there is that that the plugin thinks that it's connected to Dimenisons CM 2009 (between 10 and 12), but that's probably just a minor bug. I don't think it's affected the command-line used adversely. Everything else looks fine, and there's no error information to work with.

One thing you could try is to check that `darius.jar`, `dmnet.jar`, `dmclient.jar`, etc. that you installed into the plugin are all the correct versions from the Dimensions CM server version you are now running (it's easy to forget to update them when updating the server), but this is grasping at straws.

If that doesn't help, then all i can do is spend some time to add a flag in a new version of the Jenkins Dimensions plugin to use `dmcli` command to run a local UPDATE instead of the Java API, so you can see if that helps.

Hi dconneely , I checked and verified the jar files are up to date and using the same ones from Dimensions CM and they are. This hasn't been a huge issue (although would be nice to have fixed), as normally we can just kick the build off again and then it'll work the 2nd time. Today the same project build has now errored 3 times in a row, which has never happened before.
