NSAPI connector for Solaris9 i386 doesn't detect that one of workers is down (in loadbalancing mode), still tries to send requests to it. Tried to stop all workers with the same result, JK Status Manager (http://dev66.mw.lab.eng.bos.redhat.com/jkmanager/) shows that worker/workers status is OK.

This problem was mentioned in two comments https://jira.jboss.org/jira/browse/JBQA-3087?focusedCommentId=12515669#action_12515669

For testing is available only one machine with Solaris9 i386 so this issue can't be verified on other machines. There is also possibility that something is wrong with dev66.qa.atl.jboss.com because Sun Java System Web Server 7.0 can't be started and Tomas Herfet couldn't find the reason (as I know).
