XA Server Stops Responding to Client Requests

XA Server Stops Responding to Client Requests

PROBLEM/NEED

The XA Server service stops responding to client requests.

POSSIBLE CAUSE 1: The XA Credential Provider is eating up memory on the server

In some older versions of the XA server (4.1.3 and older), having the XA Credential Provider enabled on the XA server eats up memory over time (each time a user authenticates using remote authentication). In this case, you may see errors similar to the ones below:

Faulting application name: svchost.exe_Schedule, version: 6.1.7600.16385, time stamp: 0x4a5bc3c1

Faulting module name: eXactaccessCredentialManager.dll, version: 4.5.0.860, time stamp: 0x00000000

Exception code: 0xc0000005

Fault offset: 0x0000000000032480

Faulting process id: 0x1310

Faulting application start time: 0x01ce8eb2d87e43b0

Faulting application path: C:\Windows\system32\svchost.exe

RESOLUTION 1:

1. Disable the XA Credential Manager on the XA Server.
   NOTE: Removing the credential provider removes the ability for Connectors to make use of the user's AD username and password, but ONLY ON THE XA SERVER, where it should never be needed.
