After upgrading my single-node instance to 1.0, I'm still seeing the "timeout
when storing" issue. Here are the changes I made based on everyone's
suggestions (much appreciated!):
- Ubuntu 11.04 (natty) 32-bit
- Python client 1.3.0
- /etc/riak/vm.args: -env ERL_MAX_PORTS 32768
- /etc/default/riak: ulimit -n 32768
Here's the /var/log/crash.log report:

IIRC, {error, emfile} indicates that the max # of ports (in the erlang
VM) is being exceeded. Try bumping up ERL_MAX_PORTS in vm.args.
