Hello,
I have have a box terminating openVPN connections and after an
upstream router rebooted suddenly
I salw a klog error followed by an alloc_subregion error followed by
extent_alloc_subregion error
the OpenBSD Box ram s ram (according to the hypervisor) was not
completely used up...
is there any other reason why the error below can occur ...
are there any sysctl settings changes I need to condsider to avoid
this error in future ...
Thanks
Tom Smyth
