[Xitami] Where do requests for GET /default.ida come from in access.log

[xitami@lists.xitami.org]

I am running the xitami server and only have one problem, or maybe it's not a problem but if somebody could explain it that'd be great.  In the access log there are MANY instances of the following line:

128.211.240.66 - - [20/Aug/2001:18:52:40 -0500] "GET /default.ida?XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX%u9090%u6858%ucbd3%u7801%u9090%u6858%ucbd3%u7801%u9090%u6858%ucbd3%u7801%u9090%u9090%u8190%u00c3%u0003%u8b00%u531b%u53ff%u0078%u0000%u00=a%20 HTTP/1.0" 200 0 "" ""

Does anybody know what that means?  I get about 10 an hour and from different IP addresses, but most (not all) start with 128.x.x.x  Is this a problem?  If not, is there a way I can not log it?  Log files build very quickly like this.

Thanks for any help anybody can give me.
