Rfc destinations hangs until restart

Hi Experts,

We have a big problem here on our pi 7.0 sp25

Quite often, the rfc destinations of type tcp stop working. When we test the connections at the sm59, the transaction hangs indefinitely. Every pi interface that use the rfc adapter get timeouts.

After the restart of the server, everything works fine during sometime, and then, again, the rfc destinations crashes.

This happens 2 or 3 times each week...

¿Anybody knows what can be happening?

Thanks in advance.
