Yes, I've already increased the heap size settings using ANT_OPTS to be able to run my tests at all. Actually they run only if the max. heap size is at least 1.5 GB. I'd like to understand, where all the memory goes and how to avoid such heavy memory usage.

I resolved the issue by increasing the java heap size. There may be other related compilation tasks, but bottom line is the Java Heap Size is too small. To increase it, you need to add $ANT_OPTS to your environment. For e.g:- ANT_OPTS="-Xmx1024m -Xms512m" Thanks & Regards, Hitesh Gupta On Tue, Mar 16, 2010 at 6:17 PM, Michael Zwick <[email protected]<mailto:[email protected]>> wrote: Hi, I know, memory has been an issue on the list a couple of times. But I could not find answers to my questions. My case: When running our WebTest Suite (with webtest R_1758) during the nightly builds the resident memory consumption goes up to almost 2 GB. That's clearly too much and a knock out for Canoo WebTest and plans expanding the suite in the future in my company. Some details: There are 800 steps in total. The tests are organized as recommended like |-- allTests.xml | |-- Verify_blabla.xml | |-- Verify_blublu.xml | |-- ..... (about 15 additonal Verify_....xml files) | |-----------------| about 10 WebTest tasks in each of the Verify_...xml files | |-----------------|--------| every WebTest task with 5 to 25 steps At the end I get a single test report for the suite. I monitored the memory consumption with JConsole. What I see is a steady increase over time. In the manual it says: "When your test suite grows beyond some thousand steps consider using more than one file for collecting the reports." I'm not at the 1000 steps limit yet, but still, what does that mean? Is the recommendation to split up the test suite into various separate ANT projects? How do other people cope with this sort of thing? Any other people having memory issues? Anyone else running a large test suite? I'd be curious to find out more about the experiences of others with large tests suites and their memory consumptions. Thanks, Michael
