For this error, please refer below step to solve this issue. 1. Check the Dek machine 'asmdekeventfolder' share folder permission (Read permission). 2. If this issue still happens when you can access the share folder, please check the 'Event.dat' file size. (you can create a new file with same name when this file size is very big)
