Strange error increasing memory limit

Question

I use a shared hosting environment, and the default limit for PHP is 32 MB. I ran into some problems installing Concrete5.

When I try to enter the Concrete5 admin panel, it gives a memory limit error Allowed memory size of 33554432 bytes exhausted. Therefore, I increased the memory limit from ini_set('memory_limit', '128M')to 128M . After that, I get the error message:

Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without 
sending any data.

I tried to reduce the memory limit to 96M, 64M and some other values, but the same error is repeated (ERR_EMPTY_RESPONSE).

What is this error and why does it occur when I use ini_set()?
