[hobbit] Hobbit server doesn't start on CentOS 5 with hobbit-4.2.0 installed

No, I didn't make any changes - it's just apache and, particularly, otrs
that are using a lot of shared memory segments (mostly of 1 byte each).

It is quite likely that the RPM is just fine, but it isn't a 100% sure
thing...

Sebastian - did you make any changes to those kinds of things after
installing CentOS5?  I've installed Hobbit on half a dozen machines loaded
with CentOS5 and I've never seen this issue or had to change any such
option.

I haven't bothered trying the RPM again now that I have the source compiled
version working, but there is probably nothing wrong with it. (I never
suggested there was.) Or, at least, the RPM was not what was causing the 
problem I had - indeed the problem I had could have happened on any version
of Linux, etc..
