Whether ALTQ generates " No buffer space available " error or IPFW ?

[samira]

Hi everyone,
I using FreeBSD9.2 and defining a rule in ipfw that divert tcp packets on
port 80 to port 8000 and by suricata will be reviewed.
ipfw list:
01901 divert 8000 tcp from any to any dst-port 80

And then the packets is sent by altq to queue defined
ipfw list:
03009 skipto 3011 tcp from any to any dst-port 80
03010 skipto 3012 ip from any to any
03011 allow altq http-gbeth3-out ip from any to any via gbeth3 out

And we limit bandwidth in pf.conf for http traffic
pf.conf:
queue http-gbeth3-out bandwidth 50Kb  hfsc (  upperlimit 50Kb )

When the transmission of huge amounts of http packets and pf action is to
drop packets, suricata crash and the following message appears in the
suricata.log file:
<Warning> - [ERRCODE: SC_WARN_IPFW_XMIT(84)] - Write to ipfw divert socket
failed: No buffer space available

Has anyone dealt with this issue?

There is a similar problem:
By sending ICMP packets to the queue and send ping from the interface also
seen this problem  and the following message is displayed:
 ping: sendto: No buffer space available


If the specified bandwidth increased and not drop any packets, this problem
does not occur.

Thank you for all of your comments and help
