what is the binary protocol port?

Link,

The port for binary protocol has not changed in the new 1.6 release. Can you please send more diagnostic information which you can get by clicking on "Log' -> Generate Diagnostic Report" on the left side panel of the Membase console.

Thanks

Bhawana

Hi Bhawana,

I sent you email with attached diagnostic. I did another test where I telnet'ed into memcached and added a key/value pair without a problem. I telnet'ed into membase and did the same, and it failed. See output below:

Telnet into memcached...

ubuntu@domU-abc:/tmp$ telnet localhost 11811
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
add mykey 0 60 11
hello world
STORED
get mykey
VALUE mykey 0 11
hello world
END
quit
Connection closed by foreign host.

Telnet into membase...
ubuntu@domU-abc:/tmp$ telnet localhost 11211
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
add mykey 0 60 11
hello world
SERVER_ERROR proxy downstream closed
quit
Connection closed by foreign host.
 

This is running on 64-bit ubuntu 10.04.

Any thoughts?

Link,

This is likely because the underlying Memcached server is not running properly. 

Make sure that you have the  default bucket created.  Also, please run '/opt/membase/bin/ep_engine/management/stats'  through the telnet interface to Membase.  

Also, Please check http://wiki.membase.org/display/membase/Common+Errors and make sure that your are not facing one of the errors described here.

Hi Bhawana,

Thank you for your help. I looked around and found at lot of

   errorContext                                                child_terminated
   reason                                             {badmatch,{error,closed}}
   errorContext                                                        shutdown
 

in the log. So, I figure the easiest thing was to restarted from scratch. I uninstalled membase and then reinstalled and reconfigured on ubuntu 64-bit 10.04:

ubuntu@...21:~$ sudo dpkg --purge membase-server
(Reading database ... 36895 files and directories currently installed.)

I installed the same way I did it the first time, and as documented, without errors displayed:

I used the console and configured, taking all defaults. The following error message showed up in the Cluster Overview:

Membase Server Alert
An error was encountered when requesting data from the server. The console has been reloaded to attempt to recover. There may be additional information about the error in the log.

I checked the log in the console, and got...

I stopped the system and changed the /etc/security/limits.conf for grins, even though it was not the same error code 71. restarted the server, and the same thing.

This is a default installation on ubuntu. I made no changes to the system at all. The ubuntu server image is straight from ubuntu, no mods. Any ideas on how to proceed?

Hi Bhawana,

I think I figured it out, but it should not matter. I did not take all the default values. I change the path of the database location on the first screen to a directory that was on a different device, and I did not change the ownership permission to be membase. However, not error was reported anywhere regarding ownership or that it could not write to the directory.

Thanks.

 I had the same problem but changing the permission of the folder to membase fixed it. It was also in a different device (EBS)

I think I have simillar problem.

The connection is getting terminated in every second when I telnet.

I can also see the connection reset message appearing on top of the Administrative console.

/var and /var/opt are owned by root and

/var/opt/membase is owned by membase

drwxr-xr-x 3 membase membase 4096 Jan 24 22:07 membase

I have this user created and  /etc/security/limits.conf has the following entries

membase              soft    nofile  10240

membase              hard    nofile  10240

Can you please suggest me a fix for this issue? I am using Membase 1.6.5

Thanks
