Yes,
I think your suggestion of supporting the logging/tracing of long DNs makes
sense and we probably have to
treat that as a defect also, to get it in to 4.5 since 4.5 FC has already been
set.
But it is then a different defect.
We also need to figure out (in principle at least) why this crash occurs.
At least if it is easy to reproduce.
There are other defect tickets related to strange crashes of the IMMND like
#1043
indicating that we probably have some heap or stack overwrite somewhere.
The problem seems introduced in 4.5 and these crashes occured when not testing
any long DN as I understand it.

Hmm, then we need to re-understand and gather more evidence whether the problem
is with logtrace or somewhere else!

gcc 4.9
setup : 1 controller
changeset : 5454 and included patches for longDns
Test:
1) Create a object A with longDN value
2) Create a object B(not longDn) with parent A ie [B,A]
3) Delete the object created in step 2 ie [B,A]
