I'm seeing some sendto: No buffer space available errors along with some ssh
session hangs. The symptoms are intermitent and look a lot like this
thread.
http://monkey.org/openbsd/archive/misc/0309/msg00827.html
The system is 4.1 stable generic with the sangoma wanpipe driver. Most
traffic is moving between the t1 card and em0.
Is this probably an irq issue?
If so,
Is there any reason not to put the nics and the wic on the same irq? (is the
context switching advantage still valid?)
Does it make any real difference what the other controllers are on as long
as they avoid each other and em*, bge0, and sdla1?
If its more complicated than that, can anyone point me to some docs?
thanks in advance
