Performance trouble on AMD64 webserver
Hi, I've an 2 processor Opteron server (Sun v20z) with 4GB of RAM. It runs FreeBSD 5.4-PRERELEASE. Everything is roses for 1-2 minutes after starting Apache. Then the server freezes for 10-20 seconds then resumes normal operation and chokes every couple of minutes. I tried with 512 and 1024 httpd processes running. It is a fairly dynamic webpage. Apache is coupled with mod_php. Each process takes 18-19MB of resident memory. I was tuning the machine after getting the nefarious "collectng PV entries ..." message. I tried to increase PMAP_SHPGPERPROC and all. It doesn't make the performance better. Snapshot of vmstat -z gives: ... PV ENTRY: 48, 4312872, 1611440, 616384, 8657151 The free value decreases to something close to 0 then the machine chokes to get back up to some large value. My loader.conf: accf_data_load="YES" accf_http_load="YES" kern.ipc.nmbclusters="131072" kern.maxusers="1024" The sysctl.conf: kern.ipc.somaxconn=1024 The customized part of kernel config: options VM_BCACHE_SIZE_MAX="(500*1024*1024)" options MAXDSIZ="(1000*1024*1024)" options MAXSSIZ="(1000*1024*1024)" options DFLDSIZ="(1000*1024*1024)" options PMAP_SHPGPERPROC=4096 options PMAP_SHPGPERPROC=16384 options SHMALL=131072 options SHMMAXPGS=131072 I've also removed lots of SCSI hardware, Wifi and USB parts which I don't need from the GENERIC config. Any Ideas how to make it work?

The only key which works on the box is BRS, which doesn't give me sufficient interaction with the system. I've skipped morse code lessons and boy scouting in my life altogether. /S -- SÅawek Åak / UNIX Systems Administrator ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"

I'm running serial console on these toys now. No problem here. BTW Beware of the shitty virtual CD/Floppy drives on the server. There is no way to turn them off from BIOS. Had no luck with hints either. 5.3 fails to boot on them so don't even try it. 5.4 spits out some warning messages during boot about them but then runs fine. Don't know about CURRENT. /S -- Sławek Żak / UNIX Systems Administrator ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
Diskless boot problem
Hi, I have a problem with booting Dell 2850 over network. The machine reads kernel over net, boots upto mounting / from NFS and then crashes. Tcpdump output: 12:15:58.919683 arp who-has 10.158.190.73 tell 10.158.190.74 12:15:58.919702 arp reply 10.158.190.73 is-at 00:11:43:d3:6e:e1 12:15:58.920058 IP 10.158.190.74.475209176 > 10.158.190.73.2049: 92 getattr [|nfs] 12:15:58.920134 IP 10.158.190.73.2049 > 10.158.190.74.475209176: reply ok 28 getattr ERROR: Stale NFS file handle 12:15:58.920432 arp who-has 10.158.190.73 tell 10.158.190.74 12:15:58.920442 arp reply 10.158.190.73 is-at 00:11:43:d3:6e:e1 12:15:58.920681 IP 10.158.190.74.475209177 > 10.158.190.73.2049: 100 lookup [|nfs] 12:15:58.920707 IP 10.158.190.73.2049 > 10.158.190.74.475209177: reply ok 28 lookup ERROR: Stale NFS file handle 12:15:58.920932 IP 10.158.190.74.475209178 > 10.158.190.73.2049: 100 lookup [|nfs] 12:15:58.920963 IP 10.158.190.73.2049 > 10.158.190.74.475209178: reply ok 28 lookup ERROR: Stale NFS file handle 12:15:58.952180 IP 10.158.190.74.475209179 > 10.158.190.73.2049: 100 lookup [|nfs] 12:15:58.952277 IP 10.158.190.73.2049 > 10.158.190.74.475209179: reply ok 28 lookup ERROR: Stale NFS file handle 12:15:58.984785 IP 10.158.190.74.475209180 > 10.158.190.73.2049: 100 lookup [|nfs] 12:15:58.984866 IP 10.158.190.73.2049 > 10.158.190.74.475209180: reply ok 28 lookup ERROR: Stale NFS file handle 12:15:59.020500 IP 10.158.190.74.475209181 > 10.158.190.73.2049: 104 lookup [|nfs] 12:15:59.020573 IP 10.158.190.73.2049 > 10.158.190.74.475209181: reply ok 28 lookup ERROR: Stale NFS file handle 12:15:59.054130 IP 10.158.190.74.475209182 > 10.158.190.73.2049: 104 lookup [|nfs] 12:15:59.054224 IP 10.158.190.73.2049 > 10.158.190.74.475209182: reply ok 28 lookup ERROR: Stale NFS file handle I wonder where the `Stale NFS handle' error comes from, as the client doesn't seem to have mounted the filesystem over NFS from what I can see. On the console of the diskless I have this: NFS ROOT: 10.158.190.73:/var/www/FreeBSD-5.4-x86-PXE em0: Link is up 100 Mbps Half Duplex exec /sbin/init: error 70 exec /sbin/oinit: error 70 exec /sbin/init.bak: error 70 exec /rescue/init: error 70 exec /stand/sysinstall: error 70 init: not found in path /sbin/init:/sbin/oinit:/sbin/init.bak:/rescue/init:/stand/sysinstall panic: no init Uptime: 55s Cannot dump. No dump device defined. Automatic reboot in 15 seconds - press a key on the console to abort The speed for em0 is obviously wrong. Setting on the switch is 100 full-duplex. Our network wizards can f***kup autonegotiation on Cisco Catalyst, so it must stay that way. Intel em-s tend to hang for a couple of seconds before getting on the net so it might be the problem. On the other hand kernel loads just fine over TFTP. Any thoughts?
