out of memmory error

[maxsap sapranidis, módosítva 13 év-val korábban]

Hello I am following this
example, but I am stuck at this step:

Expand portal and double-click all.

After help I received from this forum I have succesfully set ANT_OPTS to 1024 and 256 mb of ram, but when I double click on the run ant starts and after about 3 minutes I get this message:

I changes max head to 1536 but the error insists, has anyone encountered the same error?
regards maxsap.

Hi maxsap,

I have tried to recreate this issue several times without success. My guess is its environmental. I currently compile Social Office on a machine with 4 GB's of memory. The process tends to use most of that memory so perhaps if you are running less than that its running out of memory?

Thanks,
Jamie

I have 2 gigabytes of ram but in the system monitor shows that while build runs only 500 mb are allocated then the error occurs. Also I am running under ubuntu 10.10 and using suns version of java, I have tried to install ecj wondering if this could resolve the issue but no success so far.
regards maxsap

Anyne, any idea? I have tried to install ecj as mentioned, followin istructions from this link. No luck so far, when i change the build.properties to use ecj I get an error that ecj is not installed.
