SVN server error: Provider encountered an error while streaming a REPORT response. [500, #0]

Question

We run a Linux SVN server (Apache/2.2.22 (Unix) DAV/2 SVN/1.7.6 mod_ssl/2.2.22 and OpenSSL/0.9.8x) and we sometimes get the following errors in the error log files.

The clients use a JAVA application that synchronises data from the repository via HTTPS. The client application uses the following components:

• svnclientadapter-1.8.0.jar
• svnjavahl-1.7.4.jar

Log file shows:

[Thu Apr 24 21:03:39 2014] [error] [client 70.198.65.85] Provider encountered an error while streaming a REPORT response.  [500, #0]

Does someone have any idea ? Thank you in advance

Try to install apache2-mpm-prefork on svn server, if you don't have it yet, in ubuntu it can be done with

sudo apt-get install apache2-mpm-prefork

We had similar problem, in our case this problem appeared when we had more than one client at a time.
