[Linux-HA] CVS HEAD ccm dumps core

I've had to ditch using 2.0.2 because certain fixes weren't present. Using 
HEAD last week worked fine but this week I can't get my two node cluster to 
run at all.

The first problem I can see is that ccm dumps core continually on one node. 
The stack trace is

#0  0x001ce402 in __kernel_vsyscall ()

The services don't come up on the other node but I thought this needed 
addressing first.
