Usage Note 45020: "UNABLE TO OPEN/READ MESSAGE FILE USING THE -MSG PATHS" message
When you launch a SAS®
process in a UNIX environment, the following message might appear:
UNABLE TO OPEN/READ MESSAGE FILE USING THE -MSG PATHS
One cause of this message is malfunctioning UNIX file locking.
You can test to determine whether UNIX file locking is causing problems by invoking SAS with the FILELOCKS option set to a value of NONE:
sas -filelocks none
Set -FILELOCKS NONE only as a test.
If you update a SAS data set while the setting is in effect, data corruption
If setting -FILELOCKS NONE enables you to invoke a SAS session without errors,
ask your UNIX system administrator to recycle the daemons
rpc.statd, rpc.lockd, and nlockmgr on both the host and on
the NFS client.
