After installing a new kernel and checking all the kernel settings, we
discovered that overcommit was set like so:
vm.overcommit_memory = 2
vm.overcommit_ratio = 90
setting it back to the default makes the fork issues disappear!
Now we have an issue with the max concurrent checks, but I'll start a
new thread for that.
Thanks for the help everyone!
