AcidMaps crashes Tomcat

[4ilin]

AcidMaps doesn't work with our layers. Is there any known limitation on number of points in a layer?
Tomcat goes out of memory (more than 1Gb).

Our infrastructure:

• Tomcat 7.0.22
• Geoserver 2.1.2 Stable
• Acidmaps 2.0 geoserver plugin (acidmaps-2.0.jar)
• JNI lib - Windows 32bit
• Java - 1.6.0_20 32bit

We've tested on two OS:

• Windows 7 Pro 64bit
• MacOS X 10.x

We get following errors:

Hi, there is a known issue when the result generated from the DB exceeds the memory available in your system.
If the problem you describe doesn't happen with smaller datasets it can be the same scenario.

Also there is a solution to this case designed but we haven't had the time to implement it.

In order to determine if this is the problem, can you please check that with smaller datasets the service works fine?
