Hello, I am currently experiencing an issue with FreeBSD 9.0-RC2 r227852 where the net.inet.tcp.reass.curesegments value is constantly increasing (and not descreasing when there is nominal traffic with the box). It is causing tcp slowdowns as described with kern/155407:
Exhausted net.inet.tcp.reass.maxsegments block recovering tcp session (for this socket and any other socket waiting for retransmited packets). After exhausted net.inet.tcp.reass.maxsegments allocation new entry in tcp_reass failed (for this socket and any other socket waiting for retransmited packets). I have increased the reass.maxsegments value to 16384 to temporarily avoid the problem, but the cursegments number keeps rising and it seems it will occur again. Is this an issue that anyone else has seen? I can provide more information if need be. Thanks, Kris _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
