Loads of Non HTTP errors in performance test
Hi,
I conducted a performance test with 400 users (2 mins delay in each
request).
I am getting the following Non HTTP errors for many requests:
1.
Response code: Non HTTP response code: java.net.UnknownHostException
Response message: Non HTTP response message: staging.nsonline.org.uk
2.
Response code: Non HTTP response code: java.net.SocketException
Response message: Non HTTP response message: Too many open files
I have seen similar posts on these exceptions, some suggesting using HTTP
Request HTTPClient sampler. Some using latest version. Some suggesting
checking Server Limits. Some suggesting increasing the number of sockets for
jmeter.
- I am already using HTTP Request HTTPClient sampler.
- I am having latest version of JMeter.
- The Server Limits is for supporting thousands of users.
- I do not know how to increase the number of sockets for jmeter (Can anyone
tell me how can I do that).
I am giving requests to Server via a proxy server.
Regards,
Harjit Singh

hi
UnknownHostException is just that the name could not be translated into an
ip address, you might try to change it into the actual IP address and see if
you get any errors.

Re: Loads of Non HTTP errors in performance test

Thanks for the reply deepak. But these errors are coming for subset of
requests to the staging server, so it is not related to resolving address...
I will check about ulimit and will see how to configure it...

Hi
1. It looks like whatever machine you are running JMeter on cant resolve
staging.nsonline.org.uk . You'd need to ask your admin to make entries into
hosts or use IP address .
2. Your unix machine probably needs some ulimit tuning to increase file
descriptors, Im not a unix guy so I dont remember the exact parameter names
, but Im sure you'll get this on google / your unix admin
