Re: my cluster spontaneously loses a node after ~48hrs
Bryan- thanks for this tip, i probably wouldn't have suspected ulimit. It's been 4 days now since my last restart, which i've never reached before. so i'm cautious to say that the problem has gone away. i suspect this progress is due to some library updates we performed on the hosts. it turns out some of them were out of date, which i wan't aware of. we updated them all at once, so there's no way to identify which one(s) caused the problem, assuming that was the problem. hopeful now, ~ Jason On 12.05.2015 05:37, Bryan Hunt wrote: Also ensure ulimit is set according to the recommendations on docs.basho.com. ulimit set too low is a common cause of node termination.

Re: Java client 1.1.4 and headOnly() in domain buckets
Hi Daniel, do you have reasons not to upgrade to the latest driver. I know
the semantics have changed somewhat. Are you running a fork of the client?

Hi all
Am I right thinking that v1.1.4 does not support headOnly() on domain

During domain.fetch() line 237 in

there is no check/call headOnly() on FetchMeta object.

Re: No WM route
This error is usually caused when `admin.listener` is configured in
riak-cs.conf. Either remove that line from the configuration file, or use
that IP and port for your create user request.
Please let me know if that helps you out
