Thanks for reporting this issue. I just did some debugging on my
system and I think I was able to reproduce this issue. It seems as if
I made a tiny mistake in how I implemented the RFC 5426 UDP message
size limiting. Could you please give the following patch for syslogd a
try?

It should be sufficient to apply this to just the 'client' syslogd.
There is no need to patch the central (storage) server.
