Hey,  
I have a problem with the f5-LTM of my Logstash environment.  
I got 5 servers with Logstash installed, and the LTM doesn't work with more than 2 servers.

I sent big mass of http requests to check my Logstash environment, and there is a data loss when the LTM pool contains more than 2 servers.

It doesn't matter which one of the 5 servers will be in the LTM pool, still the same problem occurs.

Is it a known problem, configuration, or a LTM issue?

Any guidance will be helpful.

Thanks 🙂
