Hi Ablet,

do you remember which activity you were trying to change?

Ablet,

Could you also please turn on debugging, try the problem again and then attach the logs here?

The instructions for creating the debugging logs are in the Creating DEBUG Logs page on the wiki.

LAMS may run a bit slower while the debugging is turned on, so when you have posted the logs here, you will need to turn debugging off again (that is, set Threshold back to "INFO")

As for how LAMS is running in general, it is hard to say without knowing what else is running on the PC. I have run LAMS fine with that much memory, but if I am running another program that takes a lot of memory then the PC has problems. What apart from LAMS are you running anything on the PC?

Thanks for posting the logs and the other error. I think it is the amount of memory allocated to Java that is the problem.

I assume you starting LAMS by running "run.sh" in /usr/java/jboss/bin?

If yes, then follow these instructions:
* take the attached file "run-lams.sh" and put it in /usr/java/jboss/bin.
* make the new file runnable ie "chmod +x run-lams.sh"
* now start LAMS using "sudo ./run-lams.sh".

If you are not using run.sh, but instead are using the wrapper then please let me know as we need to change a different file.
