However, I'm a little confused: You indicate that dumpcap memory usage is growing but you then say you're "using the unencryption feature of the packet dissector" which is not in dumpcap but is in wireshark/tshark. Wireshark/tshark memory will increase as a function of the number of packets dissected. That's the nature of the beast. ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev@...> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request@...?subject=unsubscribeOk, I'll run it again and see if I observe the same behaviour. It was definitely dumpcap which had high memory and cpu usage. Sorry, I mis-understood what was going on with the dissectors, I thought that if I ran the capture through Wireshark the captures would be decoded, I was wrong as the raw packets were output to file (obviously).
I should have been clearer in my original rely. Wireshark runs dumpcap to do the actual capture. Dumpcap writes to a file and Wireshark reads from the file. So: When running a cature through Wireshark, the catures are decoded (by Wireshark). ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
