Intermittent "SVNException: svn: E175002: Connection reset" when updating workspace from Jenkins via SVN

Question

I have Jenkins (2.138.3) running on a Virtual Machine.

On another PC on the same network, I have a Visual SVN Server (3.9.2).

Intermittently (maybe 25% of the time), the checkout fails with the following error:

ERROR: Failed to check out https://path/to/my/repository
org.tmatesoft.svn.core.SVNException: svn: E175002: Connection reset
svn: E175002: REPORT request failed on '/my/repository/!svn/vcc/default'

Anecdotally this seems to happen more often if more-than-one project is building simultaneously.

I am using Subversion 2.12.1 in Jenkins. I have tried updating from an older version of Jenkins (~6 months old) but still have this problem.

Users checking out code from the repository have not experienced these problems, however.

Answer 1

The error is produced by SVNKit which is used in Jenkins to enable SVN client capabilities. This problem seems to be specific to SVNKit because the problem does not reproduce with native Subversion clients.

To resolve the problem, add the -Dhudson.spool-svn=true option to Jenkins. See https://issues.jenkins-ci.org/browse/JENKINS-1260.
