Netdump

Hi,
I cannot perform a netdump crash over the network. I configure one server as Netdump Server and other server as client of netdump.
I can do the following success steps:

- echo 1 /proc/sys/kernel/sysrq
- echo m /proc/sysrq-trigger


- echo 1 /proc/sys/kernel/sysrq
- echo h /proc/sysrq-trigger

But, the following fails:

echo 1 /proc/sys/kernel/sysrq
echo c /proc/sysrq-trigger

In the client console, the last message that I can see is "performing handshake with client", but the netdump never begin.

I´m using RH3 EL Update 3 and the version of netdump/netump-server is 6.0.11.3

The hardware is BL20p G2 and the NIC is a Broadcom Gigabit. No Vlans. ASR (Automatic Server Recovery delay is 10 minutes)

Any Ideas?

Note: In my own machines, with the same netdump configuration, I can perform a netdump crash. (my own machines are RH3 EL Update 1, same version of netdump), no gigabit.

Thanks in advance
