error_log file, what are these errors?

[Anon]

In my error_log file:

./zend-scanner.l(1337) : Freeing 0x0887078C (73 bytes), script=/export/nola/myp
age/index.php4
./zend-scanner.l(1337) : Freeing 0x083416C4 (73 bytes), script=/export/nola/myp

./zend-scanner.l(1337) : Freeing 0x085C3644 (73 bytes), script=/export/nola/myp

Is it referring to not freeing the mysql queries??

Thanks
