Mind sharing the proxy rules? From your strace looks like you get file not found error for the bot urls so might be something related. Also maybe more detailed description of your setup might help like how many servers and apps you are running is the database on the same box is the same apache a proxy as well and any other third party stuff you might be using.

The strace will only show mmaps until "[crit] Memory allocation failed" ! Do you have a suggestion on how I could "intercept" these processes before the problem happens ?rlimit maybe. I'd suggest something is trying to allocate a 'negative' amount of memory. The real answer is to locate the bug. If you really want to do that, build/install debug versions of your s/w, attach gdb to the running process, and ask for a backtrace.Update :
Just to let you know, we use proxying to serve http://requests/like/that to customers while internally getting http://requests?like=that if you see what I mean
Could it be the source of a problem ?Denis
