Queue Error in Jmeter
Hi Team
I am working on a lottery project and using jmeter to do a performance test.
I am conducting a performance test on teh API's.
I have a total of 48 thread groups with each thread group having a sign on
request.
When I try to run with 100 users the sign on request is failing with the
below error.
{"code":39,"message":"Pending acquire queue has reached its maximum size of
32","source":"auth"}.
The API's are working fine, I guess I have some issue with the tool.
Please let me know if you need any further details.
Thanks
Rakshita
SV: Queue Error in Jmeter
Posted by Christian Gerdes <ch...@skatteverket.se.INVALID>.
Sounds to me like there is a limit set in the API on how many concurrent authentication requests you can have from a single IP address or something similar. Try to see what happens if you run from more than one jmeter instance on two separate IP adresses, can both run successfully with up to 32 concurrent requests?

Ämne: Re: Queue Error in Jmeter
Yes, I have this Sign on API which I use to generate numerous transactions.
Suppose I am adding 100 users, out of 100 at least 20 would have failed the request with this error.
I had googled about this and this is the solution I got, which doesn't seem to work.
*This error message typically occurs when JMeter is trying to acquire more connections than are available in the authentication queue. The authentication queue has a maximum size of 32, so when JMeter tries to acquire more connections than this limit, the error message is displayed.*
*To resolve this error, you can try the following:Increase the authentication queue size: You can increase the size of the authentication queue by adding the following line to your JMeter properties file:*
*httpclient4.max_persistent_connections_per_route=your_value*

Ok, you're hitting a limit in your API server's workload. This is what
you're using jmeter to find. It may be that no other apps are putting as
much of a load as you are with jmeter. You need to tune your load test
according to your needs. You need to have some kind of metric that you are
trying to hit. So in short the issue is not JMeter. JMeter can generate a
lot of load and can easily overwhelm a server with requests.

Is this a response from the API your testing? that doesn't look like
anything we would typically see in jmeter logs.

Hi Team
Thank you for the response.
Sign on request API can handle numerous request and that has been tested as
well. Also spoke to the API developer regarding this.
Only when I run the same api in Jmeter by adding lid on it, it’s through
an error.
Thanks

Hi Rakshita,
It sounds like you have reached the limits of what the sign on request api can handle.
This isn’t a tool issue.

Hi Team
I am working on a lottery project and using jmeter to do a performance test.
I am conducting a performance test on teh API's.
I have a total of 48 thread groups with each thread group having a sign on

When I try to run with 100 users the sign on request is failing with the

I don't see any issue with the tool, I see that your "queue" (whatever
it is) is accepting only 32 connections and you're trying to use 100
concurrent users (if not more)
You either need to amend the "queue" configuration so it would accept as
many concurrent connections as you're trying to create.
Alternatively you can limit JMeter's throughput to the value the queue
accepts, it can be done using JMeter Timers:
https://www.blazemeter.com/blog/jmeter-timer
For example if you add the Synchronizing Timer
https://jmeter.apache.org/usermanual/component_reference.html#Synchronizing_Timer
as a child of the Sampler which performs the login and set the "Number
of Simultaneous Users to Group by" to 32 JMeter will perform login in
"chunks" of 32 users at the same time.
