Corrupt CascadeInfo.cas file results in failure of cascading functionality

Issue

Cascading functionality is lost due to a corrupt CascadeInfo.cas file.

Solution

If the CascadeInfo.cas file is corrupt due to a power failure or any reason, cascading functionality will not be available.  This issue only applies to network licensed products and does not affect stand-alone licensed products.

Example:

Given the following cascading sequence and a license server with a license for Product B & Product C:

Product A -> Product B -> Product C

Cascading failure may present itself in the following way:

Startup Problems:

Scenario 1: A product that did not have its own license and that was previously starting by using a shared license through cascading will fail to start.

Example: The Product B license is available on the server.  If the CascadeInfo.cas file is corrupt, Product A will not start on license B.

Example: The Product B license is borrowed to a system where Product A is also installed.  If the CascadeInfo.cas is corrupt, Product A will not run on the borrowed license.

Example: If Product B is already running and CascadeInfo.cas is corrupt, Product A will not share the B license and will fail to start.

Wasted licenses:

Scenario 2: An already running product will fail to cascade up to and share another license.

Example: Product B is already running then Product C starts up.  If CascadeInfo.cas is corrupt, Product B will not switch over to share product C's license after a few minutes.

Expected Log File output

Here is the expected log file output.  You should see a fatal error message with a vendor id of 10 (eVendorIDCascade) and a vendor error of 6 (ADLM_CASCADE_STATUS_DECRYPTION_ERROR).  It will also be followed by an AdlmInt error of 47 (ADLM_STATUS_ERROR_CASCADING_OPERATION) or 2 (ADLM_STATUS_INTERNAL_ERROR).

WorkAround

The current workaround it to rename/remove the corrupt CascadeInfo.cas file following these steps.

1. Return any borrowed licenses
2. Check in any checked out licenses and exit all Autodesk products
3. Rename or delete the corrupt CascadeInfo.cas

The CascadeInfo.cas file can be found in the following locations:

Windows XP:

C:\Documents and Settings\All Users\Application Data\Autodesk\Adlm

Windows Vista and Windows 7:

C:\ProgramData\Autodesk\Adlm

Mac:

/Library/Application Support/Autodesk/Adlm/.config

Linux:

/var/opt/Autodesk/Adlm/.config
