Download latest version of SVN client (1.6.1). Installed on Windows Vista, all service packs/hotfixes installed. 32 bit version, 4 GByte RAM, plenty of disk space. Added about 13,000 files in multiple directories to the repository. Then committed those additions. Sending content fails with out-of-memory error. The bug is reproducable. Memory usage for this operation is predictable: about 1 KByte per added file, e.g. 1 GByte for about 1,000 files. Memory consumption can be observed with system tools. Impact: Can't add large number of files in one commit, e.g. when migrating old projects to Subversion. A similar problem existed in the past, see Bug #1964. The root cause might be different this time. Will try 'import' instead as a work around.
