It's been nearly a week that the problems appearing in the website (movable type based) do leave such lines in stderr.log

All i know that previously to this i attempted to change php.ini settings in order to permit bigger uploads. I read that out of memory can derive from some disproportion between php.ini settings and litespeed - in fact the memory i/o buffer was 60 while i had set the memory_limit in php.ini up to 128M. Now it is lower, it actually is 50 M but the problem continues to occur.

Any idea why this is happening? Or what other clues should i look for to understand it? Thank you in advance
