For all users using the RXF C V8.0.7 and prior V8 versions, it is highly recommended to update to version 8.0.8 or newer because of a bug inside the timer manager.
The bug could occur when stopping an UML timer with another UML event. While stopping the timer by a user task, the timer task driving the UML timer could interrupt the stop operation of the user task and corrupt the linked list of timeouts in use and the depending message queue of an expiring UML timer.
The bug could cause problems very rare, what is the reason why it is discovered that late.
For any questions regarding this problem please contact the support @ firstname.lastname@example.org.
