Many threads appear to be waiting on the same instance of
org.apache.tomcat.dbcp.pool.impl.GenericObjectPool in
org.apache.tomcat.dbcp.dbcp.PoolingDataSource.getConnection, while I can
see only 4 threads actually doing database work.
Is it possible that you have configured too few database connections?
(If the current limit is 4, try 20.)
A second point of contention looks like
at neo.util.Mutex.aquire(Mutex.java:77)
at
neo.xredsys.presentation.ArticlePresentationManager.getArticle(ArticlePresentationManager.java:200)
at
neo.xredsys.presentation.ArticlePresentationManager.getArticle(ArticlePresentationManager.java:169)
at
neo.xredsys.presentation.ArticlePresentationManager.getArticle(ArticlePresentationManager.java:149)
But this may be a property of the software you use and harder to change.
