Mongo failing connection on 127.0.0.1/localhost

[Amnon]

Hi All,

I'm having some problems with mongo connection to local machine , this
configuration runs on my testng runs and i'm failing about 5/10 times
with :

Caused by: com.mongodb.MongoException$Network: can't call something :

Now this is the stack trace from my ec2 build machine but it's also
happening on my own local machine and other developers machines ,
we are all running different OS (osx,ubuntu 11.04/11.10,windows 7) we
are all using mongo 2.0.1 (tried different versions and it also
happened) ...
I've tried both with localhost and 127.0.0.1 and nothing helped i
can't find anything in mongodb.log , is there any known issue with
local connections ?
of course that mongo is up during that time and i can connect to it
from the command line and if i re run the tests it works.... for some
reason localhost connections are off and on with the java driver ...

Can you please paste the section of your Java code where you are
creating the connection to Mongo? It should be something like:
Mongo m = new Mongo("localhost", 27017);

Do these errors occur right when the connection is being made, or do
they appear at a later point in your application? If so, what is the
operation that generates these errors? Can you please paste that
code?

Are you running mongo on the default port, 27017?

Thanks.

Hello

I think my problem with the elasticsearch river is related (2.0.4 64bits + 2.7.2 driver)
