Re: 503 Service Unavailable + Stop Responding
Hi, its running correct. no such messages in logfiles. Im still having the second problem, that the varnishd just stops responding on port 80 and all requests die. maybe ill switch to 2.0.4, and check it out on high load.

varnish stopps responding with no reason
Hi, im was running squid3 for a while now, but now i tested varnish, to cache my cdn. Following: proxycache1:/var# varnishd -V varnishd (varnish-2.0.3) The Server is Debian Etch 4.0 incl. all official updates. It has 24GB of RAM with 64Bit CPU. I compiled and installed varnish with no errors. And it is running on one of my 2 Servers like a charm! load of the server + delivery of my static files is great. But i have a problem on the other machine, its exact the same. I start varnishd like this: varnishd -a :80 -b 89.xxx.xxx.xxx:80 -s malloc,15360M storage_malloc: max size 15360 MB. Using old SHMFILE Im not using a config yet, since i only have one backendserver for static files. In Log i see: Mar 31 12:56:34 proxycache1 varnishd[4608]: child (4609) Started Mar 31 12:56:34 proxycache1 varnishd[4608]: Child (4609) said Closed fds: 3 7 8 10 11 Mar 31 12:56:34 proxycache1 varnishd[4608]: Child (4609) said Child starts Mar 31 12:56:34 proxycache1 varnishd[4608]: Child (4609) said Ready Then i change my application-config to use the 2nd varnishd as proxy two (actually have an array of ips for my CDN). All went well, it delivers fast. After a few minutes it stops responding on Port 80, localhost + ethXips not working but Varnishd still running. telnet give me timeout. ps auxf: root 4608 0.0 0.0 98196 944 ?Ss 12:56 0:00 varnishd -a :80 -b 8xx.xxx.xxx:80 -s malloc,15360M nobody4609 0.2 0.4 398384 114996 ? Sl 12:56 0:03 \_ varnishd -a :8xx.xxx.xxx:80 -s malloc,15360M I switch all traffic over to the other varnishd and its running smooth again... I activate squid on the other server, and all works smooth again. any ideas? regards -- Sascha Kain IT / Administration eraffe media GmbH Co.
