Have you ever been plagued by persistent unexplained lockups on your Sage MAS90 file server? One client recently had some rather consistent issues with their server locking and refusing to budge further without a re-boot. One call to Sage technical support uncovered a very interesting solution that you may want to try on your server (but only if you’re having problems).
You’ll know if you’re possibly impacted by this issue because shortly after one user freezes in MAS90, other users on your network will report issues and become frozen as well.
This is not always a server issue. There can be other causes such as bad cabling or faulty network hardware.
In at least one situation that we’ve seen the cure to the persistent system crashing file lock problem in MAS90 had to do with Opportunistic Locking which is turned on by default in most newer implementation of Windows Server.
Microsoft has a knowledgebase article on this available here:
As with any changes that you make to the system registry, proceed at your own risk and only with knowledge that incorrect modification of your system registry can cause potential issues with your system.
If you are working on MAS 200 and having problems with the Application Server crashing – especially with large numbers of concurrent users – please see our article on setting up the Sage MAS 200 Application Server the proper way.
