I am having some issues on a server where multiple Apache processes are being spawned and eating up the physical memory and swap.
httpd process consumes around 130MB of RES. However, PHP's
memory_limit is set at 32MB.
The initial thinking is that there is a memory leak in PHP code - however, I don't see any particular code that could be causing this... granted the codebase is not necessarily efficient, however, what other explanations are there for such large memory consumption by Apache given memory_limit is set quite low?
