While posting "picking list journal" in AX the attached RFSmart scanner is getting hanged.  RFSmart scanner is working properly at other times but daily at around 5 pm it stops working.  I could see lot of warnings in Event viewer:

I have pasted the warning below, could any one help how to solve this issue:
