Hi,  
I have upgraded to Gatling 3.0.0 RC4 today and executed one of my scenarios. I have executed this scenario many times in Gatling 2.3.1 without any problem. In Gatling 3.0.0 RC4 I ended up with OOM after approx. 25 minutes.

java.lang.OutOfMemoryError: Java heap space  
Dumping heap to java\_pid24502.hprof …  
Heap dump file created [1302179725 bytes in 11.259 secs]

Load setting - nothing fancy …

setUp(scn.inject(**rampUsersPerSec(1) to 5 during (30 minutes)**))  
.protocols(httpProtocol)  
.uniformPauses(50) // percent

Take a look at heap dump - looks like none of the sessions are being garbage collected …

The scenario is pretty standard, the only extras I can think of are in configuration: output to Graphite is ON and logging of failed responses is ON. Also, I use 2 feeders (CSV and custom Range).

Happy to provide more details, just tell me what you need.

Cheers  
Jan

I will send a download link on your email. Do not want to make it public.
