That would certainly explain why your system isn't generating traps!

What is the output of a full walk of the 1.3.6.1.4.1.2021.15 tree?
What O/S are you working with?
What version of the Net-SNMP agent are you using?
What is the exact size of the file "/var/lib/mysql/Syslog/SystemEvents.MYD" ?


Unfortunately the fileTable code doesn't include much in the way of
debug code, so it's a bit difficult to track exact what it is actually doing
(as opposed to what it should be doing).

But try compiling and running the following code fragment;

   int main( int argc, char *argv[] )
   {
       struct stat sb;
       int ret;

       ret = stat( "/var/lib/mysql/Syslog/SystemEvents.MYD", &sb );
       printf("stat returned %d,  size = %d\n", ret, sb.st_size >> 10);
   }

What does that display?
