A while ago I had to disable APC for PHP as it was resetting every minute or two. It's only now that I've traced it to an LSWS update. The details: 1) I'm using the 32-bit version and the bug is there both in the Standard and Enterprise editions. 2) PHP 5.3.8 with APC enabled works normally under 4.1.9, APC goes nuts if I upgrade to 4.1.10 or 4.1.11. 3) Compiling PHP 5.3.10 and switching to it under LSWS 4.1.11 does not help - APC still crashes. Please help .
