man ulimit -> set or report file size limit
How would this help?

This will be used by apache (RLimitCPU) in srclib/apr/threadproc/unix/proc.c

This will be used by apache (RLimitMEM) in srclib/apr/threadproc/unix/proc.c


As I understand you, the only possibility to solve my problem is to patch the
php source.
If I search in the php code after RLIMIT_ the only occurences are in ext/posix/posix.c
The RLIMIT_* are used there by posix_getrlimit (Rem: there's no posix_setrlimit).

Or is there another possibility?
