Description

Doing first experiments with Subversion 1.10, I noticed the following behavior. Obtaining a svn log via svnserve gets stuck after several calls and the following error appears in svnserve.log:

6988 2018-05-16T12:42:34.687777Z 10.123.10.21 - polarion/data/svn/repo ERR - 0 200002 Serialized hash malformed value data

This error occurred both then loading complete svn log for a location via svnserve from Polarion application (uses SVNKit 1.9.1) as well as loading next 100 entires of svn log via TortoiseSVN 1.10. Playing with the configuration reveled this error only occurs when using dynamic caching (-M 0 parameter) and changing to 1.7 caching (-M 128) resolves the problem.
