I have the same issues but on Windows Server 2008 R2 SP1.
Internal error: Revprop caching for 'E:/csvn/data/repositories/repo/db'
disabled because SHM infrastructure for revprop caching failed to
initialize.
Internal error: -Can't open file
'E:\\csvn\\data\\repositories\\repo\\db\\rev-prop-ato
Two months ago I have upgraded my Subversion Edge from 3.x (1.7.5) to 4.x
(1.8.4) running on Windows Server 2008R2 SP1.
After upgrade all seemes to work fine.
But soon our developers began complaining on a very low commit speed.
After checking log files I have found thousands of identical errors
