Facing 'Unable to lock the input folder' __FCLOCK.LCK (Access is denied) error on File connector

Hello All,

We have poller configurations enabled for File connector in HA environment(2 nodes). When we restart the SCs, file connector will pick the files from filesystem. After some time it will stop picking the files. In log file we often see 'Could not create Socket Writer URI ' and Unable to lock the input folder error. Can some one suggest how to resolve this issue?
