L+G E650 System.OutOfMemoryException

Hello,

we were reading data from L+G E650 while we stopped readout without closing connection and after that we are not able to establish new connection (using serial port). After trying to establish connection we get System.OutOfMemoryException . Is there anything we can do in this matter? Basically SNRM request is sent, next UA reply and next after request a very strange frame is transmitted having a lot of "01 0D". The log is as follows:

12:50:35 Initializing serial connection.
12:50:40 Send SNRM request.
