Hi

I am having intermittent problems with a stonebeat FC installation - the
control/protocol network appears to die for no apparent reason. When this
happens, both nodes think that they are the only online node, with obvious
disastrous consequences for sessions.

The setup looks more or less like this:

                        outside network
        ------------------------------------
           |                                       |
        *-----*  control/protocol net   *-----*
        | FW    |-----------------------| FW    |
        | 1     |               |               | 2     |
        *-----*         |               *-----*
           |                    |                  |
                           *-----*
                           |       |fw management
                           |       |
                           *-----*
                                |

The control/protocol network has 192.168.0.0/24 addresses, connected via a
cisco catalyst 2900 switch. All ports on the switch and all machines are
forced to 100fullduplex

The following shows up in /var/adm/messages around the time where things go
funny:

--------- on node 1 ----------
Dec 12 13:13:33 node1 unix: NOTICE: sbif: node 1 suggests that node 2 will
be marked offline (5,6988,6990,0,0,0)

--------- on node 2 ----------
Dec 12 13:13:26 node2 unix: NOTICE: sbif: node 2 suggests that node 1 will
be marked offline (5,6988,6990,0,0,0)

According to stonebeat support this error indicates "some sort of problem
with the control network"

The installation runs on 2 Sun E220's (2x 450Mhz, 2Gb RAM, hme0, 2x qfe
card) with solaris 2.7 (latest patches), Stonebeat is v2.0.2035, fw-1
v4.1sp2, with a management station running Redhat 6.2

Anyone seen this before?
