getnewaddress blocks

Question

Hi,

I have a program that executes 4 getnewaddress commands in sequence. The fourth one blocks. Once this has happened, a curl invocation for the same command blocks.

The body looks like this {"method":"getnewaddress","id":":4","params":[],"chain_name":"chain1"}

Attempting to kill the server with ctrl-c fails. kill -9 works. starting it up again we get

----

I think this is a red-herring perhaps. Waiting a moment, the restart works.

Any help much appreciated.

thanks

Farzad.

Hi
We think we've reduced this down to an issue with the http client in vert.x. Apologies and thank you for your help.
kind regards

Answer 1

Thank you.

Some setup notes:

Using latest version of vagrant 1.8.1 and virtualbox 5.0.10 on OS X 10.11.3.

Vagrant file uses latest ubuntu/wily64.

The client is written in JDK8 using Vert.x 3.2.1.

As mentioned the first three http json-rpc requests work successfully. The fourth locks.

thanks
