KNOWN ISSUESThis program and/or components uses select(2) to wait for packets and there may be an internal delay within that call during startup that results in missed packets. As a workaround, set pcap_thread_timeout ( see dsc.conf(5) ) to a relevant millisecond timeout with regards to the queries per second (QPS) received. For example if your receiving 10 QPS then you have 20 packets per second (PPS) and if spread out equally over a second you have a packet per 50 ms which you can use as timeout value. Since version 2.4.0 the default is 100 ms.BUGSFor issues and feature requests please use:https://github.com/DNS-OARC/dsc/issues
