[Dspace-tech] DSpace error

Hi

Does anyone know what the error below relates to? we've had these errors
occurring intermittently today - perhaps tomcat needs a re-start?

Naveed,

Funny, we just started getting the same error intermittently today, as
well. For us it's only happening once every few hours.

I've been digging through our logs for more info. For us, these errors
*always* occur from the same web crawler/bot, which is identifying
itself as:

"Yeti/0.01 (nhn/1noon, yet...@naver.com, check robots.txt daily and
follow it)"

I've been searching around on this bot now. There's some indications
that this may just be a bad bot:

I'm not sure if this is the same problem you are seeing, Naveed?

- Tim

By way of additional evidence:

An internal server error occurred on http://minds.wisconsin.edu:

Ramped up earlier this week; I'm getting one three to five times an hour now.

Hi Tim,

Yes, same problem - our apache access log shows the bot:-

61.247.217.34 - - [20/Nov/2007:20:06:18 +0000] "GET /robots.txt HTTP/1.1"
200 166 "-" "Yeti/0.01 (nhn/1noon, yetibot@

naver.com, check robots.txt daily and follow it)"

I'll block this IP.

Thanks,

Naveed
