Hi,
I get errors when loading files in rtc-scm called by jazz build. The message is: "Unable to load file somefile.zip. Reason: An existing connection was forcibly closed by the remote host." Here is the exception: 2010-07-19 11:30:51,138 WARN com.ibm.team.scm - Unhandled Exception ClientAbortException: java.net.SocketException: Connection reset by peer: socket write error at

Here is the error message printed by jazz build

I solved this problem by moving the sync host to rtc server box.
I created a small test project on rtc with only one file rt.jar. When I tried to load this file (cli and jazz build) from a different machine other than the server box, I always got that connection error. Here is our environment rtc 2.0.0.2 ifix3 on windows 2008 64-bit MS SQLServer 2008 Express/Enterprise Tomcat and JDK are the ones shipped with rtc |

Sorry, Tomcat is the 64-bit version, not the one shipped with rtc

Is there anything relevant in the server or DB logs? Errors like this sometimes indicate that the server is under heavy load, and/or experiencing frequent DB issues making requests take longer due to many retries. It could also indicate issues with network connectivity, particularly if it works better when on the same machine. Is there a firewall in the way when using separate machines?

Looks like it's failing on .jar and .zip files. Are these all large files? Does it work OK for smaller files?

Hi,
Thank you for the reply. Yes all the errors I got are on .jar and .zip files. File rt.jar is 10493K. Flat files and small binaries are fine. I checked with our technical analyst. Firewall should not be a problem. But I cannot verify this myself. Lin Looks like it's failing on .jar and .zip files. Are these all large files? Does it work OK for smaller files? |

Do you still see the problem if you use the out-of-the-box configuration for Tomcat etc.? Anything in the server/DB logs?
