For what it's worth, I also ran into the problem with the Cygwin setup updater hanging during the man-db update.
I'm on Win8.1, using Cygwin 64-bit. I didn't have GDB installed, so checked with Process Explorer, the mandb.exe process was using CPU, but I didn't notice a particular file handle open. The /var/log/setup.log.run.XXXX is at http://pastebin.com/pZyc2iWf I've installed GDB, if there's any particular steps I can take to attach to mandb and provide better information (stack traces / variable contents) please let me know. -jon -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
