I have a Jenkins v2.107.2 instance (running as a Windows service) which is checking out several projects via Subversion from a Visual SVN Server (on a seperate Windows PC).
One of the projects (the largest - ~2.7GB) is occasionally, but then consistently failing with the following error when attempting to checkout:
ERROR: Failed to check out https://example.com/myrepo
org.tmatesoft.svn.core.SVNException: svn: E175002: CRLF expected at end of chunk: -1/-1
svn: E175002: REPORT request failed on '/svn/REPO/!svn/vcc/default'
at org.tmatesoft.svn.core.internal.wc.SVNErrorManager.error(SVNErrorManager.java:112)
In addition, when checking the logs of the Visual SVN Server, I can see the following:
Error writing base64 data: The timeout specified has expired [500, #70007]
A failure occurred while driving the update report editor [500, #70007]
Provider encountered an error while streaming a REPORT response. [500, #0]
Previously, some combination of downgrading Jenkins & the Subversion plugin by one version resolved this error, but despite having not changed versions since, this no longer works.
From looking online, there seems to be some sort of timeout built into Subversion where requests will be killed if going over a certain time. However, the instructions all refer to the Subversion config that should be in %APPDATA%\Roaming, which I do not seem to have.
The Jenkins Subversion documentation suggests C:\Windows\SysWOW64\config\systemprofile\AppData\Roaming, but again I have nothing there.
I've installed TortoiseSVN, which did create the Subversion configuration folder. I've modified the http-timeout, and then put this configuration in all the locations suggested by the documentation, but this has not made any difference (but whether it's because it doesn't fix the issue, or it's not being picked up - I'm not sure).
You need to enable spooling.
See this Jenkins support issue, although this dupe issue describes the solution better:
Set the
-Dhudson.spool-svn=truesystem property or increase timeout on the server.
