Can anyone help me with this?

Thanks

Increase the amount of memory allocated to Subsonic.

If you tell us what platform you are running Subsonic on it would be easier to be more specific.

I use 4.7 and i have increase this memory to 1024 do have any idea how much i must increase the memory?

[bushman4]

You shouldn't need anywhere near that amount. Try dropping it to 512.

And to help further I'd need to know what platform (ie, Windows standalone, Tomcat hosted on Windows, etc...) you are running on, not what version of Subsonic.

A google search for the error message (it seems a bit different than "usual" OutOfMemoryExceptions) gives a couple of interesting answers.

my first hit for example: http://stackoverflow.com/questions/1281 ... g-zip-file

This seems more related to the platform you're running on than a software bug to me.

I have this problem and when the memory max was at 512 i increase this to 1024 but now i have again this problem... i hosted in Tomcat server.

Thanks for your help:)

"Java HotSpot(TM) 64-Bit Server VM warning: Attempt to deallocate stack guard pages failed."

Most likely you have Java related problems. Default memory settings are usually adequate since moving most functions into the db since 4.7. I"ve never had to use more than 256 even when trying to overload the program by accessing multiple library copies.

You've been asked but fail to identify your platform details, so further assistance would just be a guess.

I usually recommend a careful reinstall by removing ALL Java components, then installing the latest release for your platform. If that doesn't work, you may also need to do the same with Tomcat and Subsonic.

Remember that Subsonic will have problems with Tomcat 7, so use Tomcat 6.

Good luck.
