Question:  All of a sudden all the processes fail with GC overhead java heap space OutOfMemory errors. What is the problem?
Answer:  According to the process reporting and process log, the failure is on a SFTP connector  SFTP connectors will attempt to build a list of 65000 files that exist on the remote directory. In this case, there was no file filter set and the Max Files to Read was set to 0, which means the process attempted to read all available files.


Solution:  Once the Max Files to Read was set to 1, the processes did not run out of memory or failed with GC overhead.
