I had problems similar to yours
=>there have been problems in former lps-versions which might block you from
loading images/whatever data. It can crash the application if you load an
image while the image before has not completed yet, also i have the feeling
that the image-loading is much fast now.
My solution is to have some loading bars while loading and to use the latest
OL-version

2007/5/31, Nguyen Ngoc Phuong Thao <[EMAIL PROTECTED]>:
Hi,
I'm using OL 3.0 for my application. I've met this problem for 2 weeks and
still cannot find out the solution. My application reads image url from an
xml file and display them on a view. Everything is ok on my local site, but
there are 2 errors which ONLY occur on the site which has many users access
at the same time.
Case 1:
The image with size 2.19 MB, 1910 x 2245 cannot be showed on the view.
Case 2:
Sometimes images are overlaped together on the view.
When viewing log file I saw this error message:
29 May 2007 22:50:17 (124.197.59.89 972350) INFO cache.Cache -
