HAproxy, failed: No buffer space available (errno=55)

[pino121]

PFSENSE Version 2.4.4-RELEASE-p3 (amd64)
Package HAproxy 0.59_21

Goodmorning everyone,
I have a small problem for a few weeks, when I add sites in haproxy and restart the service I get this message:

[ALERT] 022/080837 (901) : sendmsg logger #1 failed: No buffer space available (errno=55)

The problem is not blocking, the server has a lot of free space.
Thank you
