iplanet 6.0 error log entries for .gif files

[Masaki Birchmier]

I am getting an error log entry every time a gif file is called for on my iplanet 6.0 sp2 webserver (HP-UX 11.00). The files are there and load just fine on the browser.

The 3 errors that I keep seeing are...
=========================================
GET /fte/gifs/nav_up.gif, jrNSAPI[1880] reports: Couldn't initialize from remote server, JRun server(s) probably down.

GET /dst/bxz30web/img/img8.gif, jrNSAPI[3616] reports: could not open : Error 0, trying to bootstrap from

GET /dst/bxz30web/img/img8.gif, jrNSAPI[3616] reports: Can't persist servers, null server list.
====================================

I have JDK/RTE 1.3.1.01 installed.

Does anyone have any suggestions on what could be causing these errors?

Thanks in advance,
Masaki
