Comment 3 for bug 1673281

Hi, thanks for forwarding it upstream.
The solution is even better than any bump of the default value, it is now dynamic.
See the upstream ticket
https://community.openvpn.net/openvpn/ticket/873

"Someone needed to write code to make the internal structure dynamic ("just make it big" is usually a waste of memory for most users, and still too small for some others, so it needs to be re-coded to be more dynamic).
This has now happened and will be in 2.6.0, to be released in the coming weeks."

And 2.6.x is in Ubuntu Lunar (2.6.1) and Mantic (2.6.5).
Hence while this was not tracked touched for a while it is fixed in those releases.

This needs to be considered for an SRU where the new code does not exist and it would be a trade of memory vs ability.
