Closer inspection of the network trace indicates that syslog-ng is in
fact doing the right thing when using log_fetch_limit(1), generating
one syslog UDP packet per input message. Apologies for the noise.

It is my concentrator (Splunk) that is concatenating messages received
within short time intervals into single events which made me believe
that log_fetch_limit(1) wasn't taking effect.

Thanks for the support,
