What ethereal version were you using? All three of your captures decode
without error with my fairly recent one.


Ethereal version I used was older one.
Here's the ethereal version I used.

# tethereal -v (RedHat EL3)
tethereal 0.10.8
Compiled with GLib 2.2.3, with libpcap 0.8.3, with libz 1.1.4, without
libpcre,
without UCD-SNMP or Net-SNMP, without ADNS.
NOTE: this build does not support the "matches" operator for Ethereal filter
syntax.
Running with libpcap version 0.8.3 on Linux 2.4.21-32.EL.

I've checked CSS's capture data with newer version ,
there were no messages  "malformed packet".

# tethereal -v (CentOS 4.2)
tethereal 0.10.13
Compiled with GLib 2.4.7, with libpcap 0.8.3, with libz
1.2.1.2,
without libpcre, with Net-SNMP 5.1.2, without ADNS.
NOTE: this build doesn't support the "matches" operator
for Ethereal filter syntax.
Running with libpcap version 0.8.3 on Linux
2.6.9-22.0.1.EL.
