I am running the binaries provided by gaven for 0.7.2rc2.
I started bitcoind with -detachdb=1 just to test whether everything was working well. On first attempt I got:
mike@alpha:~$ ~/bitcoin-0.7.2/bitcoin-0.7.2rc2-linux/bin/32/bitcoind -detachdb=1
terminate called after throwing an instance of 'boost::exception_detail::clone_implboost::exception_detail::error_info_injector<boost::system::system_error >'
what(): mutex: Invalid argument
I think started again with detachdb=1 and everything seemed fine. I shut down and no issues. I started again and everything fine and shut down with no issues. So this happened once and I can't get it to happen again. I am using 32-bit debian.
