today i have got this warning :-/

But i have:

It's a debian unstable ;-)

I know this issue and some sysctl's were converted to procfs in 0.3.58. However, on pre-2.6-someting kernels nginx uses sysctl() to get /proc/sys/kernel/rtsig-max and /proc/sys/kernel/rtsig-nr values in recovery process of rtsig queue overflow. I need to investigate whether repeated pread() syscall on /proc/sys/kernel/rtsig-nr file could replace sysctl().
