UID and GID errors
 

Our error log is showing a huge amount of errors, they all display the same details -> " as UID 32561, GID 32563 " and in most cases also show the referrer.

/forums/index.php" as UID 32561, GID 32563
/forums/forumdisplay.php" as UID 32561, GID 32563
....etc.

Can anyone please shed some light on this and let me know where I should be looking to correct this problem.

Forum usage does not appear to causing any problems for users and our members have not reported any problems.

TIA
