Could not load class: modTransportPackage from mysql.

Finding these lots of these enties in my error-log:

[2012-07-04 12:59:03] (ERROR @ /index.php) Could not load class: modTransportPackage from mysql.modtransportpackage.

[2012-07-04 12:59:03] (ERROR @ /index.php) modTransportPackage::load() is not a valid static method.

I don't know how to debug this? there is no reference in my index.php to modTransportPackage??

Any hints on how to debug/fix this? I have runned the installer, but the error still fills up the error log....

No idea what is going on without more details. What version? Which distribution? When does this occur?

MODX Revolution 2.2.4-pl (traditional)

I guess it happens on every page refresh?

Same thing is happening to me:

MODX Revolution 2.2.4-pl (traditional) so same version as described above.

Any suggestions?

I have this ones too a lot in 2.2.5-pl (advanced and traditional)

Do these occur when loading Package Management?

no it looks like it's happening on every page on the front-end pages.. at least; I have cleared the logs and immetiately it's back several times

Why would your front-end be looking for transport packages?

I don't know.. I do nothing in the manager besides reloading the error log page. I know this site has a lot of visitors on a day (talking about 3000 a day).

Maybe it's coming from a component which does something weird?? I don't know.. the logging is very crap about where the error is coming from.

I discovered a system setting to scale the error level to "fatal" and that makes my log not grow so fast or even better stays empty.
