Too Many SEUM Agent Processes

I've been working with Solarwinds support to try and resolve this issue, but so far we haven't had much luck.  Wanted to see if anyone else has encountered this issue before and found the solutions.

As of about a month ago, we've been experiencing issues where none of the SEUM transactions have been playing on time.  A reboot of the SEUM server will resolve this issue, but it isn't really a good long term solution.  When this occurs we see a very large number (70+ usually) of processes called SolarWinds.SEUM.Agent.Worker.exe in the Task Manager.  If I kill all of these processes it again resolves the issue:

C:\Documents and Settings\sreno>tasklist /FI "IMAGENAME eq SolarWinds.SEUM.Agent.Worker.exe"

Image Name                     PID Session Name        Session#    Mem Usage
========================= ======== ================ =========== ============
SolarWinds.SEUM.Agent.Wor     3928                            0    290,356 K
SolarWinds.SEUM.Agent.Wor     8168                            0    302,336 K

C:\Documents and Settings\sreno>taskkill /FI "IMAGENAME eq SolarWinds.SEUM.Agent.Worker.exe" /F
SUCCESS: The process with PID 3928 has been terminated.
SUCCESS: The process with PID 8168 has been terminated.

Unfortunately, regardless of the method used to clear the issue it just comes back after a few days.

Checking the Application Event Viewer we find a large number of Event:1000 entries leading up to the failure.  As such I've setup an event log monitor to alert us when these events start getting generated.  This allows us to preemptively kill all of the processes before they start affecting transactions.

Has anyone else experienced this and come up with a workable solution?

Technical details so I don't get asked for it
