Hi, I've been trying to use JMeter to run load tests but it seems that no matter what heap size I give it, it gradually uses up all memory and gets bogged down in garbage collects.
I am using a series of HTTP Samplers to generate roughly 50 requests a second (50 threads each generating 1 request a second). It will run smoothly enough for 5 hours or so and then it will usually begin to become unstable (requests taking longer and longer to complete, round trip times spiking for no reason, etc...). I have tried to extend the heap size but it just seems to delay the point at which everything goes heywire. Is it normal for JMeter to gradually use up all memory it has available? The only settings I've played with in the jmeter.bat file are the heap size and I've tried using one of the concurrent garbage collect schemes. Any insight anyone might have would be very much appreciated. Sincerely, Vince
