Hello: I have some issues with different versions of squid servers on FreeBSD (different versions too). they had been running without any problem, but now I am receiving this kind of message "Limiting open port RST response from xxx to 50 packets/sec". After some messages the performance of the servers decrease suddenly until lose their network connections. I have received commets of some downloader that might cause this behavior, for example, FlashGet. This is my sysctl.conf net.inet.tcp.msl=7500 net.inet.tcp.blackhole=2 net.inet.udp.blackhole=1 net.inet.icmp.icmplim=50 ; It is the limit shown on message kern.ipc.somaxconn=32768 Best Regards. Thanks in advance, Humberto
