members goes down frequently

My main switch is the following:

Switch Ports Model              SW Version            SW Image                

------ ----- -----              ----------            ----------              

*    1 30    WS-C3750E-24TD     15.0(2)SE             C3750E-UNIVERSALK9-M

The management vlan for these are on vlan 25.  The problem is that when I connect to main switch via ssh and then rcommand to switch 1 or 2, sometimes I loose my connection to the switches and my ssh connection is just cut.  When I login to the main switch I see that the member is down and keeps this for a couple of seconds (+- 25 seconds).

Can this be a configuration issue?

thanks

Can u Post Config

[steven.geerts]

do you mean the entire config?

I think the most important configuration is how both are connected right?

switch 1:

cluster enable wijgmaal 0

cluster member 1 mac-address 001f.9d2d.9f80

cluster member 2 mac-address 001f.9e2c.2180

Hope this is enough information?

When the switch via rcommand is down, I can however connect to it via ssh on it's ip 192.168.25.4

You're have 3750 and you're running switch clustering????  How quaint.

I'm suspecting that your stack cables are not cabled up properly or you have a stack module failure. 

[steven.geerts]

Hi the cabling was done correctly so the problem is not related to this.
