How much buffer can GELF hold if the network goes down?

Graylog Central (peer support)

I have setup Graylog-to-Graylog forwarding via GELF TCP (or GELF UDP).

If the network between the 2 Graylog servers is down, how much data can the sender keep before the receiver is back online?

with a TCP connection the sender will stale until the receiver is back online.

With stale I mean, it will run into serious issues because every single message need to timeout. If you have a unstable connection between both you should consider adding a queue between them.
