membase-server-ubuntu-1.6.0beta1 crashes when installed on ubuntu 10.04 lts x86_64

Stephen, it seems that we didn't control the release quite properly enough. We made a last minute decision not to include Ubuntu support so that we could ensure as successful a beta release as possible. Unfortunately, it seems that some pages didn't get updated.

Ubuntu support will be coming very shortly. I've noted your issue and will pass that along to our engineering team.

Thanks for your help and cooperation, please keep an eye out for Ubuntu support!

some more info in Ubuntu support:

Thanks Corey.

Stephen, we are in the process of officially supporting Ubuntu and it will likely be coming in the next few weeks. In the meantime, I'd ask that you follow the discussions in the membase google groups since that will more closely track the behavior of what's available in the open source.

Of course, I'll continue helping out where I can!

Perry

Just an update here...We released a refresh to the beta which now supports Ubuntu versions 9.04 and higher.

Check it out!

I tried with northscale-server_1.6.0beta3.1_x86_64.deb on ubuntu lucid 10.04 but I still get the error:

Event Module Code Time
Service memcached crashed in 0.00s supervisor_cushion001 13:14:33 - Mon Sep 13, 2010
Service memcached crashed in 0.00s supervisor_cushion001 13:14:28 - Mon Sep 13, 2010
...

Any ideas?

Cheers,
Nicolas

Ok this is how I fixed it:

In the manual, there's a nice topic about log files:
/opt/NorthScale/bin/browse_logs > /tmp/nslogs.txt

I saw a particular error message:
[CODE]ns_1@127.0.0.1':ns_port_server:107: Message from memcached:
failed to set rlimit for open files. Try running as root or requesting smaller maxconns value.
[/CODE]

In fact, in the /etc/init.d/northscale-server script there's something about ulimits but because ubuntu was not accepting it, I created an entry in /etc/security/limits.d/northscale.conf

[CODE]northscale soft nofile 16384
northscale hard nofile 16384
[/CODE]

After this, it works like a charm.

Nicholas,
Thanks for the response and continued digging, we'll try to reproduce this and have the behavior handled better for the future.

Glad you're off and running with Membase!

Perry

Nicholas, we have reproduced this and filed a bug for it ([url]http://bugs.northscale.com/show_bug.cgi?id=2338[/url])

Thanks again, please let us know if you have any other questions.
