Core ... experienced 1 failure

Some background on my configuration:

    * Flash Media Server 3.5.3
    * Service runs as a domain user with VOD files on a network share
    * ..\conf\fms.ini
      VOD_DIR = \\UNC
    * I want FMS to only bind to these two IP's

      ..\conf\_defaultRoot_\Adaptor.xml
      <!-- <HostPort name="edge1" ctl_channel="localhost:19350">${ADAPTOR.HOSTPORT}</HostPort>-->
      <HostPort name="internal_be" ctl_channel="localhost:19351">10.10.2.47:1935,80</HostPort>
      <HostPort name="internal_fe" ctl_channel="localhost:19352">10.10.1.27:1935,80</HostPort>
    * This server is used only for VOD, no custom apps or programming

The problem I'm having is that I'm getting what seems to be a Core crash every 15 or 20 minutes, the end users gets disconnected and the server comes back and they can then resume playback.

..\logs\master.00.log

(w)2581256    Core (7200) _defaultRoot_:_defaultVHost_:::_1 experienced 1 failure!    -

For each time there is a crash core.00.log and access.00.log files begins anew with their respective headings #Date: 2010-06-01 but there is no indication as to why it's crashing.

Does anyone know how to troubleshoot this further? is there a way to set FMS to log more error data?

I've been reading various posts here and elsewhere but nothing really addresses the issue.
