Can you please provide some specifics about your setup that is experiencing the problem?
HW - Sparc, PPC, Intel x86/x64, ARM ? OS - what OS is the problem occurring on? specific BIND version? anything about the NIC in question, possibly to include mfg && model number, if relevant? Thanks On 04/06/18 07:20, Ict Security wrote:
Hi guys, we are running a Bind 9.x Server, everything is going fine. Under particular heavy load mometns, with some hundreds of concurrent queries coming in, sometime Bing stops answering for some seconds or answer with important delays. But, when i try to query the same server/same Bind on a NIC alias IP during congestion on the main IP, everything is fast! I changed some tunings in: max-connections in /proc txqueue in network ipv4_ports and i mitigate something. But it is not completely solved. Do you think Bind could have some NIC IP limit? Some ideas? Really thank you! Francesco _______________________________________________
