We tried saturday to create wp-admin/php.ini and
paste this code in memory=64MB.

With increasing the memory for php the sites for now works two days without error.

What do you think?

Okay

I will try but it could be a bit tricky, there are about 42 plugins activated, so which one is it and honestly which one can I deactivate, we are in production so it could be very difficult to find it out.
Also I have to wait several hours before it errors happens. So on 42 plugins it could take days and days.

Can I not log the error in a better way?
