I moved the virtual machine where designate processes are running into a
host in the same LAN than OST. Now the designate-api process does not die
anymore (still using qpid). I'm afraid that some network problem or timeout
could be the reason for this problem. We'll keep monitoring this process to
confirm it.

I understand that it's a bug of designate-api or oslo.messaging library.
