Symptoms

On : 12.2.1.4.0 version, MFT Runtime Server

ACTUAL BEHAVIOR
---------------
MFT Is Unstable

MFT not being stable, which is causing interfaces to fail, pulling is not happening

A restart of MFT instance will fix the problem but the issue reoccurs again.

Actual issue is MFT is not polling the file from the target directory. When we restart the instance the polling of the file is happening, but the issue will remain same after few minutes.

The topology is a 2 node MFT cluster

Customer noticed this issue after applying latest CPU, they saw that

- MFT schedule every 5 min but some times doesn't work (not triggered)
- Sometimes MFT triggers but the status is active and in progress on MFT console but the file was never moved

The process failing works as follows
1. an external system puts files every 5 minutes on an NFS file system visible to both of the nodes mounted on the same directory
2. then MFT is scheduled to pull files ever 60 seconds with Minimum Age of 60 seconds as well, then they are sent to an SFTP server.
3. if one of the nodes is running this files are pulled every 5 minutes with no issues
4. if both of the nodes are running then the console shows that the files are not being pulled every 5 minutes (much longer) and they stay on Active running for a long time (like they where stuck)


EXPECTED BEHAVIOR
-----------------------
to be able to pull files with both servers up with and process them
