truss either syslog-ng or logger to see what it actually sends. log messages
might be garbled if they are around 1024 in size, since syslog-ng might also
modify it (with results in truncated messages again).
Imagine the following scenario:
- message to syslog-ng (with no host and date parts), 1024 bytes in size
- syslog-ng rewrites the messages, inserts host and date (internally these are
stored in different variables where the 1024 limit is not appliced)
- syslog-ng formats the new message (according to the template given, or the
usual syslog format) where the host and date parts of the message are
inserted, the message now becomes more than 1024 bytes, thus the message
If syslog-ng reads a message which exceeds 1024, the remaining is read as an
