No buffer space available

[dniasoff]

Hi,

I have just deployed Zabbix and loving it.

I have just hit one issue though.

I have one machine with many virtual interfaces (VLANS on etherchannel trunk)

Whenever I start the zabbix agent, my networking stops working and I get errors like this.

ssh: connect to host 192.168.1.3 port 22: No buffer space available

The OS is Debian Squeeze (actually Vyatta)

I have been running this machine for a couple of years without issues and have Zabbix working ok on other instances of this OS without as many interfaces.

Any ideas?

Thanks

Daniel
