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)
System info:
FreeBSD 8.0-RELEASE-p6 FreeBSD 8.0-RELEASE-p6
$ netstat -mb

0 requests for sfbufs denied

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.
Thanks,
Henry
