After yoiu reach InUseConnectionCount=275 on one instance the next calls to a connection will wait the 'BlockingTimeout' of the DS configuration. This will often end up in such situations, many threads are waiting for a connection and block memory and resources, the GC can not free memory, the server gets slower and you will have a crash because of too much GC load. You might - increase the number of connections   might not help because you must handle the number of threads in one instance (maybe increase memory) - add JBoss instances - limit the number of web sessions -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/732054#732054] Start a new discussion in Datasource Configuration at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
