I am having a weired problem with my infragistics. Here is my scenario, I have a dash board with 10 charts in it for each county/ states in US and this whole page calls 10 stored procs to display data, so it takes about 14 seconds to load data and display the page [out of that 13 seconds for sp's] and the data wont change for a month or so. So I updated the deployment scenario to ImageURL="ChartImages/Chart_#SEQNUM(1000).png" and also I set the @OutPut cache of the page to 5 days [60*60*24*5]. Everything used to work fine till last week. I used to observe ChartImages folder and I can see image number ranging from 0 to 999. But suddenly from yesterday I can see only images from 0 to 111. Since the pages are cached for 5 days it displays wrong charts for my selection criteria's.

Hopefully I explaind my problem correctly. ANY HELP
