thold big values problem

[dragec]

Hi!

I am using cacti h version with latest thold. And I've puted thold in work for some data sources like proc utilisation, temperature on routers and switches and so and it is working fine. Then I tried to create alert on some interfaces, considering speed and so but .... when I go to data source and click onto link that should present me screen for defining treshold setting .... I get blank screen that is opening .... opening .... and opening and never opens. After that I cannot get any graph on screen and I must restart server in order to get everything back. Any ideas?
