There were some complaints about valid setups
that ran into problems with LimitNPROC. This
is especially true since LimitNPROC limits
the total amounts of threads running for the
same uid, so if multiple openvpn services run
under the same user, they will compete for
resources. As suggested in the systemd
documentation change this to TasksMax which
really counts the threads running in one
specific service.
Also increase the limit. When using e.g.
resolvconf for DNS configuration the limit
can be exhausted just due to the amount of
nested shell scripts.
