Large SVN checkout fails sporadically

Question

I\'m currently experiencing issues during a large, full SVN repository checkout (20GB+), where the checkout process will halt randomly. The repository is composed of many small

Answer 1

I ran into the same problem attempting to do a snv checkout on a moderately sized (500MB) repository using a server consisting of Centos 7.4.1708, Apache 2.4.6, Subversion 1.9.15 and Windows 10 clients using TortoiseSVN 1.9.7 from behind an Apache Reverse Proxy.

The solution for me was to add SVNAllowBulkUpdates Off similar to teori's answer. I attempted to use "SVNAllowBulkUpdates Prefer", but when I restarted httpd, it threw an error saying "SVNAllowBulkUpdates must be On or Off". My final SVN/Apache configuration file is:

    DAV svn
    SVNParentPath /svn
    SVNAllowBulkUpdates Off
    AuthType Basic
    AuthName "SVN Repo"
    AuthUserFile /var/svn/svn-auth-user
    Require valid-user

Other thoughts: I do not believe the Timeout and AuthDigestNonceLifetime settings are directly related to the problem. I did attempt to use them but neither had any effect. I specifically experimented with the timeout, keepalive and keepalivetimeout settings on both the SVN host and the reverse proxy host.

The problem may be related to "deflating", but I also disabled it as Tim S. suggested and it also had not effect. The reason I still think it may be related is that, after eliminating the error, I noticed that the number of bytes transferred was substantially greater than before.
