DataMgr.c Line 4908 Resizing record

[Hamish McGovern]

In PalmOS 2.0 what does "DataMgr.c, Line 4908: Resizing record" mean
I'm getting this when I run gremlins.  It is the DmResizeRecord call.

I've also got another one in Edit Categories (builtin) 
"List.c, Line: 1060, Invalid item" - again generated in a Gremlins run

Is there anywhere that has an explanation of all the different line numbers
and errors that are likely to popup.
