Re: [squid-users] Diskd Message Queues and Shared memory for FreeBSD 6.x

-----BEGIN PGP SIGNED MESSAGE-----

Thank you very much to everybody for the information. I now know the
reason why Squid and the FreeBSD 6.1 box crashes every now and then
when I use aufs.

I was using Diskd for the past 2 weeks but it caused the Squid process
to be zombie when the load goes above 100 requests/second.

Also I don't see any kind of useful info on the cache.log when the Squid
process gets zombied except for:

2006/11/10 11:28:14| clientReadRequest: FD 142 (x.x.x.x:60171)
Invalid Request
2006/11/10 11:28:16| parseHttpRequest: Unsupported method 'aa
'
2006/11/10 11:28:16| clientReadRequest: FD 253 (x.x.x.x:60181)
Invalid Request
2006/11/10 11:28:18| parseHttpRequest: Unsupported method 'aa

2006/11/10 11:28:18| clientReadRequest: FD 96 (x.x.x.x:60191)
Invalid Request

I will apply the patch for aufs in my FreeBSD 6.1 (amd 64 bit) server
tonight.

For the time being, I will try to use ufs.

By the way guys, I have these compiled in my FreeBSD 6.1 kernel:


options IPFIREWALL #firewall
options IPFIREWALL_VERBOSE #enable logging to syslogd(8)
options IPFIREWALL_FORWARD #enable transparent proxy
options IPFIREWALL_VERBOSE_LIMIT=1000 #limit verbosity
options IPFIREWALL_FORWARD_EXTENDED #all packet dest changes

#DiskD Shared Memory and Message Queue
options MSGMAX=32768 (max characters in a message)
options MSGMNB=16384
options MSGMNI=41
options MSGSEG=2049
options MSGSSZ=64
options MSGTQL=2048
options SHMSEG=128
options SHMMNI=192
options SHMMAX=33554432
options SHMMIN=1
options SHMALL=8192
options MAXDSIZ=2147483648
options DFLDSIZ=536870912
options CPU_ENABLE_SSE
options UFS_DIRHASH
options KVA_PAGES=512

#other settings (requires a lot of RAM)

options MAXFILES=8192
options NMBCLUSTERS=32768


Please shed some light on this.
