The problem is that after running for 1 hour the network hangs . I have in the message log "/kernel: xl0: watchdog timeout" and in the = squid logs " No buffer space available" The system is dual xeon @500Mhz with 2.5GB of RAM and 10x9.1GB SCSI, FreeBSD 4.9-PRERELEASE from Thu Sep 11 and squid-2.5.STABLE3 build from = ports. My kernel: maxusers 256 options MSGMNB=3D16384 # max # of bytes in a queue options MSGMNI=3D512 # number of message queue identifiers options MSGSEG=3D8192 # number of message segments options MSGSSZ=3D128 # size of a message segment options MSGTQL=3D512 # max messages in system options SHMSEG=3D16 options SHMMNI=3D32 options SHMMAX=3D2097152 options SHMALL=3D4096 options MAXDSIZ=3D"(2048UL*1024*1024)" options MAXSSIZ=3D"(2048UL*1024*1024)" options DFLDSIZ=3D"(2048UL*1024*1024)" options NMBCLUSTERS=3D65535 options NBUF=3D16384 When I am port-forwarding the traffic to the squid without wccp the = machine is stable and works fine. The problem appears after setting squid with wccp and bringing gre = interfaces. I've tried different settings but with no effect. The squid passes = arround 20 mbits/s=20 with over 100 req/s. Will appreciate all advices. Best regards, ---------------------------------- Ventsislav Velkov Network Administrator Evrocom.Net +359 32 607321
