I tried doing that but it did not seem to be all that helpful for me. What kind of network bandwidth are you handling and also how many CPU cores and amount of RAM have you given to Bro I wonder ? Regards, Vikram Basu Seceon Inc. ```auto Hello there Vikram! ``` ```auto ``` ```auto We are running the same Bro 2.5.2 with pf_ring and we also had the pinned CPUs and had a lot of packet drops. ``` ```auto After a couple tests, we managed to get the packet drops to 0 by unpinning the CPU procs, letting the OS do the dirty job. ``` ```auto We have being running like that for a couple days now, without drops. ``` ```auto ``` ```auto Hope you can get it working! ``` ```auto ``` ```auto Regards, ``` ```auto ``` ```auto Felipe Tavares ``` ```auto OpenCloud Factory ``` ---
