Good $daytime,

Anybody seen this: garbled packet log lines in syslog files?

Setup

Machine: (stock) RedHat 7.1 with (stock) kernel 2.4.3-12 and (stock)
          klogd 1.4-0
Loghost: (stock) RedHat 6.1 with (stock) syslogd 1.3-3

Both machine and loghost are i686 > 500MHz, on a switched 100Base-TX LAN.

ipchains were set up on machine, with packet logging turned on.  Then,
`nmap -sS` (TCP SYN scan) is ran against it.  This yields about 2000
syslog messages in 5 seconds.

Symptom

Several lines in /var/log/messages seem to overlap each other.

1. The problem manifests itself also on loghost, to a lesser extent.  
2. Overlapping items are not the same.  This probably points to the
   client {sys,k}logd side as error source.

Any ideas?  Thanks in advance.

P.S. real IP values are obfuscated, for obvious reasons.

  Regards,
  Willy.
