[snip] As a follow-up, I set a rate limit on ports 80, 443, and 11371 to 6 requests per 30 second window. The high-speed queries ceased almost immediately and are being blocked by the firewall (they still continue making their rapid queries, but SKS doesn't see more than 12 a minute). More ordinary queries are seemingly not affected: only between one and three IP addresses are being rate limited. However, this doesn't seem to resolve the problem: SKS still pegs the CPU meter at 100% for a minute or so every minute or two, with all queries hanging until it sorts out what's going on. -- Pete Stephenson _______________________________________________ Sks-devel mailing list Sks-devel@nongnu.org https://lists.nongnu.org/mailman/listinfo/sks-devel
