| Our cache machine is a Dell Poweredge 2950 X5355 @ 2.66GHz with about
| 16GB's of RAM with 5 76GB SAS-drives. We are running Ubuntu. The server
| is serving images from the backend storage servers. The image sizes
| varys from about 10k to 200k. At peak hours we have about 4000 requests
| per second.
Which Ubuntu version are you using?
[...]
| Problem #2 is that varnish segfaults every now and then, sometimes many
| times in a short period, but sometimes it runs for a couple of days
| without problems. The only lead i have on this is
| [105474.200474] varnishd[24170]: segfault at 00000000000004a0 rip
| 000000000041ced0 rsp 00002aef65046af8 error 4
| which i got from dmesg
We have fixed some bugs which were triggered in high-volume
environments; could you see if the problem goes away by updating to
current trunk?
[...]
| I am aware that this is probably not even close to all the information
| you need, I need your help to collect more data about my problems. I
| would really like to replace squid as soon as possible.
A backtrace from when it crashes would be useful; ulimit -c unlimited
should help with that, but note that the core file will be quite large,
so you might want to try updating first.
Oh, and please file a ticket about this so we're tracking this
properly. :-)
