Deciphering (w)2581256 in the master.xx.log

Hello,

I am investigating an issue that causes an FMS core to randomly restart. During this investigation I have referenced the FMS help documentation that gets me part of the way of deciphering the issue but not all of the way: http://help.adobe.com/en_US/flashmediaserver/configadmin/WS5b3ccc516d4fbf351e63e3d119f29260bd-7ff3.html

Based on the above, it appears that (w)2581256 is a (w) warning regarding the 258 (TCServer) but what is 1256 (message ID)? Where can I look it up? Also, what is TCServer?

Some backgroud:

1. The server version is: FMS 4.5.5 r4013 on Windows Server 2008r2 x64

2. The master.xx.log shows the following during the time of the error:

#Version: 1.0 
#Start-Date: 2013-07-02 12:02:06
#Software: Adobe Flash Media Server 4.5.5 r4013 x64
#Date: 2013-07-02
#Fields: date          time          x-pid          x-status          x-ctx          x-comment
2013-07-02          12:02:04          1584          (i)2581223          Core (3016) is no longer active.          -
2013-07-02          12:02:04          1584          (w)2581256          Core (3016) _defaultRoot_:_defaultVHost_:::_0 experienced 1 failure!          -
2013-07-02          12:02:04          1584          (i)2581221          Core (4800) started, arguments : -adaptor "_defaultRoot_" -vhost "_defaultVHost_" -app  -inst  -tag "_0" -conf "C:\Program Files\Adobe\Flash Media Server 4.5\conf\server.xml" -name "_defaultRoot_:_defaultVHost_:::_0".          -

3. Outside of that I don't see any errors in the edge, access, core, or application logs around that time. I also don't see anything in the OS logs.

4. During the time, the OS CPU, Memory, and Bandwidth In/Out appear to be within reason.

5. I've taken a look through the FMS forum and although there are a number of posts that reference issues when (w)2581256 is showing up in master.xx.log, none of them seem very related to this issue, and the ones that are have no answers.

Thanks!
