I just updated my APC to 3.0.17 and now when I enter phpMyAdmin and browse around I get ==> /app/lsws/logs/stderr.log <== zend_mm_heap corrupted Not sure why only phpmyadmin has problems, luckily everything on my page seems to run fine. Hopefully it will stay that way. But the phpmyadmin bug is pretty annoying as I use it quite a lot. One way would be to go back to .16 but they did fix a big bug I had on APC on .17 so it's a loose loose situation.. Hopefully LS can make it a win win -- edit I'll just try the latest cvs php5 as this is 99% not a LS problem. Also while we are here, it would be very nice to be able to turn on debugging on sertain urls, so that I don't get flooded with debug info if I was to enable it now to debug the phpmyadmin bug. eg debug on /phpmyadmin/* and only that url.
