Increasing memory doesn't seem to increase it

Thank you for info.

Sorry, I cannot provide project, but I will send you error log. I previously noticed, that out of memory error rises when large responses are coming from server, so I set soapui preferences as following:

1. UI Settings - Garbage Collection Interval - 20
2. over TestCase Options - Discards successful TestStep results to preserve memory = true

Is there any other option I could try to set to prevent out of memory error?
Currently, I have tried following:

1. import project about 4,4 MB size to soapui and run all packages, it worked fine. I saw in task manager soapui consumes 1,13 MB
2. import project about 8,4 MB size to saopui and run all packages, it didn't work at all. I saw in task manager soapui consumes 1,17 MB.
I've got instant alert window "Exit without saving?" and Perm gen space error in soapui error log:
