Hi,

I have the same issue of OOM, but my scenario is a bit different in the sense that I am calling the same ant target multiple times in a loop and it is eating up memory every time its called in a loop.

After spending a few days trying to find a cause and solution, I came to the conclusion that there are memory leaks in Canoo, but they are not as bad, but larger memory leak seems to be in ant. It seems AntClassLoader is created everytime you call an Ant target and lingers around with all the classes, jars etc loaded in that classloader so every call to the target will create new classloader everytime!!

To get around the issue, I am planning to call ant target in a NEW VM by forking a new VM from existing one. You can probably try the same.

HTH.

Ritesh

Sorry but I don't know any webtest 1.5.1 or 1.5.4. What do you mean with these
version numbers?

Hi,

I've been using Webtest 1.5.1 for some time and it works fine for me. I then tried to use Webtest 1.5.4 and got the following error:

The little test buildfile I'm using is this:

<property name="webtest.home" value="/nf_proj/3rd_party/webtest154"/>

Appreciate any ideas on why webtest/ant isn't finding the right classes.

Regards,

Terry

does it make any change if you use depends instead of antcall?

Hi All,

I have around 45 testcases. I'm using ant version 1.6.5 and I'm getting a java OutOfMemoryError. I've read the previous archives but not been able to isolate the cause of my problem. I have set the ANT_OPTS and JAVA_OPTS accordingly to increase the heap size. I am also not using the showhtmlparseroutput option or generating a result xml report. I have defined taskdef more thab once only in 2 places. I have all the targets in one main buildfile. Only thing is that I have reused the targets using <antcall>. There are a lot of antcalls in this main build file. Could this be causing the out of memory problem. Am I missing something else which is causing this problem?

Thanks, Kashmira.
