system.log generates 6 Million lines in 2 weeks with only the date and this error:
DEBUG (7): cpid:
Why?How can I solve this problem? Thanks
If you are using the SCP extension, you should be able to find the line:
Mage::log("cpid: ". $cpid);
in the file:
You can comment it out to prevent the log file from filling up. It doesn't appear to do anything when the extension is configured and working properly.
Most likely a developer left some debug code in place. As @tsHunter mentions it sounds like somebody was debugging the SCP extension. This module uses cpid extensively (configurable product id). If you're lucky you can search your code for
log('cpid. If you're unlucky the cpid is logged from a dynamic attribute and it'll be harder to find.
