Please do the following to narrow the problem down a little:
* create the registry key HKCU\Software\TortoiseSVN\CacheTrayIcon
* set the DWORD value of that key to something else than 0
* kill the TSVNCache.exe process
* browse to your working copy with the explorer
* wait a little bit until the cache has crawled your working copy
* doubleclick on the TSVN icon in the system tray
* a window pops up, showing you all paths the cache is currently crawling
* find out which paths are crawled over and over again
* try to find out why those paths: what's special/different about those
If those paths the cache is crawling aren't even versioned, you should
exclude them from the cache (settings dialog).
