Limassol Beer Festival 2004

Limassol Beer Festival

Limassol Beer festival has started today for those of you who are interested. Posters were advertising the event for more than a month now, so I am pretty sure everyone knows the deal. If you want more information, you can browse through the festival’s website.

So far I am not planning to go. If you want to know the reasons you can scroll through my last year post. If I will hear a lot of positive remarks about this year event, maybe I’ll show up for a pint or two. Otherwise – there are better places to enjoy the company, beer, and the money.

Downtime investigated

I have investigated why the server went down today morning. Apparently, the server was a victim to a dictionary spam attack. I didn’t have any limits configured for Exim and that resulted in load avereages exceeding 60. Gucho went extremely busy another couple of times during the course of the day, but now it should be OK. I have set a few load average related limits and added few domains into the blacklist. I have also upgraded Exim to a newer version (4.40), so I hope it will run for awhile now.

# Do not do any deliveries if load average is greater that this value
queue_only_load = 12
# Do not run runq if load average is greater than this value
deliver_queue_load_max = 14
# Do not accept any SMTP sessions (except for hosts in smtp_reserve_hosts) if
# load average is greater than this value
smtp_load_reserve = 20

If anyone has any other suggestions, let me know via comments.
