Hi all,
Has anyone come across this error before:
sshd[20861]: error: reexec socketpair: No buffer space available
It stops remote users/services to connect to the machine remotely. I have
17 jails running on the machine.
CPU load on the machine is low, and RAM usage is also low (16GB avail, 5GB
Active)

What else should I be looking for to help me trouble this? I know I'm
hitting some limit, but not sure which one.
Any help would be much appreciated.

So sysctl's like net.inet.tcp.recvbuf_max might play role here, but I would
be curious as to what is the reason this comes up in the first place. Is
the traffic to system valid, and hence raising the limits would be the
correct course of action. Or do you have some deeper problem which limit
raising would only mask or temporarily alleviate the issue.
