No on Ubuntu Linux, settings:
Ubuntu 9.10 32b, 12 GB RAM, Sun JDK 1.6_22, native JAI+ImageIO, Tomcat
6.0.29, no Gdal bindings. Tomcat JAVA_OPTS="-server -Xmx1500M -Xms256M
-XX:SoftRefLRUPolicyMSPerMB=36000 -XX:MaxPermSize=512m -XX:+UseParallelGC"
I use a directory of (10) Shape files as a datastore. The problem
happens only with one Shape file (the largest: 370MB dbf).

All these Store options were disabled when the original problem occurred:
Create spatial index if missing/outdated
Use memory mapped buffers
Cache and reuse memory maps
If I enable all of these I get exceptions for all Shape files.
If I enable only "Cache and reuse memory maps" I get a new exception:
09 Dec 14:54:21 ERROR [geoserver.ows] -

This style (my SLD) has always worked and was not changed and when I use
ogrinfo -al to dump the Shape file I see that this attribute TYPEWEG is
present and has values. Strange..
best,
Just
