Unable to create log file <log file name>: <error message>.
The log directory is not valid or does not have enough disk space.
Verify the path and the directory for $PMWorkflowLogDir and $PMSessionLogDir in the Integration Service configuration, workflow properties, and session properties. The user who starts the Informatica Service on the node must have permissions to write to the directory.
Create a small file in the log directory to ensure that you are not out of disk space.
