Default error: reexec socketpair: No buffer space available

Hi guys,
I'm seeing these errors in /var/log/messages recently;
Quote:
sshd[26794]: error: reexec socketpair: No buffer space available
This leads to delays in logging in via ssh and other problems such as not being able to connect to the local database server. My initial thoughts were to look at the mbuf usage but I couldn't see any problems here;

Does anyone have any suggestions? This machine is a 7.1-RELEASE-p6

Thanks,
Chris
