It doesn't solve the problem that there is some service (probably) that is contacting AD too much and effectively doing an unintended DOS attack on your AD servers. Right-click MaxFreeConnections, and then click Modify. The network path was not found. Tim Moen Guest We get the error: "The server was unable to find a free connection 10 times in the last 60 seconds." "It's event id 2022" on one of our have a peek here
What if I see “good” and “bad” threads in my !process of the system process? A web server that connects to a database on this server works also. If this is happening frequently, you should consider increasing the minimum number of free connections to add headroom. Can i confirm that maxfreeconnections is meant to specify the maximum number of connections that the server will support? https://support.microsoft.com/en-us/kb/317249

This is Tate from the CPR team and I’m going to show you how to debug a Server Service hang and the sometimes dreaded Event ID: 2021 and Event ID: 2022.

Telnet connections and WinVNC both work to this server. Dumping out the threads… . . This output will give you a really quick look at the threads without having to .process into system, etc. Event ID: 2022 Source: Srv Description: Server was unable to find a free connection n times in the last s seconds.
This indicates a spike in network traffic. http://www.itsupportforum.net/topic/event-2022-the-server-was-unable-to-find-a-free-connection/ As more requests come into srv they will continue to get placed in the KQUEUEs by different event handler threads at the transport layer but with no WorkerThread available to process The Server Was Unable To Allocate A Work Item Server 2003 This is an oldie but goodie, but the problem is that, well it’s big and it would help to have perspective on how srv is supposed to work because all the The Server Was Unable To Allocate From The System Nonpaged Pool Because The Pool Was Empty. What you can do for this class of issue that has temporary blocking is either try again to get it in state, or have a look at the device stack that

In the Value data box, type the desired value, and then click OK. By frequency this is far and away the usual root cause for hangs of many many (did I say many?) symptom types.

Before making changes to the registry, you should back up any valued data. After a while they are able to access smoothly. http://crudlet.org/the-server/the-server-was-unable-to-find-a-free-connection.html What does this mean?
You can check out the following KBs for these configuration changes on the client side: For the client SMB side’s shell: NoRemoteChangeNotify.

I did change the registry key in the local_machine\system\currentcontrolset\services\LanManServer\Parameteras as below : MinFreeConnections : 4 MaxFreeConnections : 8 MaxWorkItems : 512 After changing, the error still persist. You could however just filter on SMB and ballpark what kind of request and from which clients are occurring most and given your client configuration if that’s normal. The number of times varies. Tighten space to use less pages.
However, in this “bad thread “case we’ve grabbed a WorkItem to process and been waiting for a long time (about 1hr 5 min.) stuck while processing it, yikes. So, what if all the threads are just waiting like in the good thread example?

This is why usually the first thing we target is filter drivers before debugging anything for hangs or if a dump is not available. So not only might we run out of the configured limits in the registry (KB317249) for srv, we might run out of Non Paged Pool, and we are definitely not giving In summary, since we can’t see further into the blocking here through SomeFiltr.sys and there’s no other threads in process with this driver in the call stack we’d recommend testing updating, Launch report from a menu, considering criteria only when it is filled… MS Office Office 365 Databases MS Access Advertise Here 666 members asked questions and received personalized solutions in the
