Goal

OSM Orders are cached in memory using JBoss, when there is request to open an order, JBoss will first try to acquire read lock on the order, however if there is on-going transaction for this order (for example, saving order/transition order) JBoss will wait for certain time (by default 15 seconds) in the hope that the pending transaction will finish during the wait;  if the transaction is not finished after the wait, JBoss will throw this exception (In this example the order is order 710, this order id will change). This is a sample error, your particular error may be different based on the version of OSM that you are using.
