check out netstat -s seeing if you can
find where it is being dropped. Also remember ethtool -s
<int> for the NIC driver level. You probably can try out
tcpdump for the capture as well seeing if you can find the
difference. Just in case, it is the problem with wireshark.

Hi Everyone,
I am running CentOS 6.3 on a HP 8200 using 3TB WD Green drives
using a EXT4 file system.
I am using Wireshark 1.8.2 compiled from source.
I am using DUMPCAP to rotate and store historical Packet Captures.
Whether I capture the packets with Wireshark or view the DUMPCAP
created file, I see dropouts in the packets being captured.
I tried to turning off journalling but this did not seem to help
much:
umount /dev/mapper/VolGroup00-LogVol_Data
/sbin/tune2fs -o journal_data_writeback
/dev/mapper/VolGroup00-LogVol_Data
/sbin/tune2fs -O ^has_journal
/dev/mapper/VolGroup00-LogVol_Data
/sbin/e2fsck -f /dev/mapper/VolGroup00-LogVol_Data
I have a attached a couple of IOGraphs from Wireshark showing the
packet drops.
Thanks alot!
-John
