Products and versions covered

Issue:

Commands in the Vault Client or the Job Processor hang and the Server does not seem to respond. There are no additional timeout messages.

  • The following error message is shown when attempting to login from the Vault client, Inventor Vault Add-In and Job Processor:
The server did not provide a meaningful reply 
The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.

Job Type error message 
  • Other error messages are visible in the Windows Event Viewer on the server:
Error message in Windows Event viewer on the server 
A process serving application pool 'AutodeskDMPool' suffered a fatal communication error with the Windows Process Activation Service.

 

  • There may be an error similar to this in the Vault Server vlogs:
...Exception: UnspecifiedSystemException [0]...
Exception(Inner): There is not enough space on the disk....

Causes:

There is little or no free disk space on either the system partition or the drives containing the Vault databases or filestores.

Solution:

  1. Install the latest updates for the affected vault server environment. 
  2. Increase the amount of free disk space or consider implementing your Disaster Recovery Plan to restore the Vault to another server with more disk space.
  3. After adding more disk space on the server restart the Vault server or run on the command line 'IISRESET'.
