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
