Jürgen, I should not have mentioned 1-wire. I was trying to indicate that there was some USB activity as well as few other processes running in the background.
The circumstances stated for having this problem is "when using threads in their application". As far as I aware my PHP script is not using threads, so I am confused whether or not my failures could be blamed on this "cache issue" or on something else not working properly in my system. I read through: http://git-public.pengutronix.de/?p=OSELAS.BSP-Pengutronix-Mini2440.git;a=blob;f=configs/platform-friendlyarm-mini2440/patches/linux-3.7/VIVT_processors.patch;h=0c67f8184579ba8558884b6ad5027d134c1e3111;hb=af7fa90298181e3419d8dafa94c6ce7793db7d6d but unfortunately am none the wiser as too how it might apply to my situation. Thanks, Dave
