Resolution:
1974-Failed to get shared memory handle for WQSINDEX

The WQS process is attempting to connect to an invalid section of shared memory.

The normal cause is an incomplete shutdown leaving files in the /var/tmp/&ltnode_name> directory.
Generally the file specific to the WQS process    WQSINDEX*_FILE

The resolution is to remove all file in the directory /var/tmp/&ltnode_name> and then start the iProcess Engine.

This issue affects iProcess Unix releases.
