When I continue to test Tomcat with libapr, Tomcat crashed.

I uses Tomcat 7.0.19 with a patch and tomcat-native-1.1.20.
http://svn.apache.org/viewvc?view=revision&revision=1148216

While a page was executing ajax requests for jqGrid jQuery plugin, Tomcat
frequently crashed and restarted automatically.

Opening a page not using jqGrid jQuery plugin, tomcat works fine.

Error messages is changed to this.

C  [libapr-1.so.0+0x1a5eb]  apr_pollset_remove+0x4b


Here is logs/catalina.out.
