java.lang.OutOfMemoryError: Java heap space during usage of KonaKart

[fizzlepop]

I am getting intermittent OutOfMemoryError errors in KonaKart. Sometimes when viewing an Address Book entry, sometimes during Checkout:

I am running with Xmx set to 32.  Is this too low for KonaKart and the KonaKartAdmin webapps?  What is the suggested memory setting?

Thanks

Yes that sounds too low - and the evidence of your exception makes that pretty clear.

The ideal setting depends on your platform and usage.  "Your mileage may vary" as they say.

Our current defaults in the download kit are:

For Windows     800m
For Unix/Linux   256m
