    Description

      The OPC UA server on host 1 and the OPC UA client on host 2. The client is connected to the server and some nodes are subscribed (monitoring enabled). Everything works fine, but simulating a network disconnection and reconnection (i.e. cable unplugged) after some seconds there's a crash in open62541.c line 41145 (method "asyncServiceTimeoutCheck"). This problem can be reproduced permanently.
