Jazz Build Engine (JBE) fails intermittently to load (fetch) files with the following errors. WHY?

2014-11-10 13:20:34 [Jazz build engine] running on host: host1
2014-11-10 13:20:35 [Jazz build engine] Accepting changes into workspace "030_XXXX-YYYY-Develop-Build-Workspace"
2014-11-10 13:20:37 [Jazz build engine] Fetching files to fetch destination "C:\Jenkins\workspace\030_XXXX-YYYY-Develop-Build" ...$3: Status ERROR: code=0 There were errors during download. 
It is recommended that components be reloaded. The reload will be incremental, loading only the missing items. You can further reduce the reload time by reloading just the projects out of sync.
null children=[Status ERROR: code=0
Failed to download /Software/Application/Aaaa/bbbb_cccc_cache.c
cannot be reached. The network stated the URL is invalid.
Error Detail: java.nio.channels.UnresolvedAddressException。
Contains : 676 .....

host A (JBE 4.0.4, Windows 7, connect to RTC4.0.4/RHEL5.7 server with VPN)            <--- Having this issue
host B (JBE 4.0.4, RHEL6.4   , connect to RTC4.0.4/RHEL5.7 server without VPN)       <--- FINE

The issue happens intermittently since Sep-08 and gets more often on host (, which was deployed on July).
It happens on all of 3 streams on host A only. The number of files each steams are increasing, and currently 600-900 files each. The only different I can see is with/without VPN connection between server host and build host.

The exceptions mentioned in your question suggest that there are intermittent network issues. A java.nio.channels.UnresolvedAddressException is thrown when addresses can't be resolved. Since the problem only manifests when running with the VPN, can you verify your VPN configuration?

So far, the hosts in the local build machine didn't resolve. I'm waiting for the customer to re-load the components.

I wonder how to check VPN configuration?....

Hi Taki, please file a defect report for this against Build or Source Control including the full stack trace from the build log. This one looks pretty odd, as if the repository URL got corrupted with XML info for the SCM file fetch request.

Hi Nick, 

Thanks for your reply. I will proceed to raise an internal escalation to investigate as a possible defect.

I just wonder.... 
How do you see "the repository URL got corrupted with XML"? which part of the URL looks corrupted?
Do you think the latency of VPN network might cause this issue?

Nick Edgar commented Nov 24 '14, 11:22 a.m.

Hi Taki, in your original post it shows the URL combined with some XML elements. It could just be a copy/paste issue, or the forum software mis-handling angle brackets.
