yes. > I've done so, but I've also added these two config options back to my config > file, and I'm seeing a lot of 'We are missing data' errors in the syslog. Such error shouldn't be related in any way with the stamps. It signals that the shared memory segment between the Core Process (which collects packets from the network) and the Plugin (which writes flows into the DB) is full. (*) It's very likely that you have not enabled bufferization. Try adding to your configuration the two following lines (then tune the parameters in order to fit your scenario): === plugin_pipe_size: 8192000 plugin_buffer_size: 4096 === CONFIG-KEYS and docs/INTERNALS give further hints and some details about them and how communication between Core Process and Plugins works. Give them a try and let me know how things get evolved. Cheers, Paolo (*) note that since versions 0.8.x, shared memory support is compiled in by default. This was not the case of previous versions that were requiring the './configure --enable-mmap'. This *might* explain why you didn't get such messages before.
