It seems that somehow mmap() is failing to set PROT_ flags on a already existing filled memory chunk... Are you sure that you are not running out of memory?

This is possible, yes, thank you.
I'll monitor and will confirm or deny.

[indutny]

Confirming or denying? :)

[drook]

Denying at the moment.
