The main issue with any iOS app is memory usage. So, it is likely that your pages are using too much memory.

Mobile Safari use some clever technique so that not the whole page has to reside in memory at any given time, only a portion of it. Maybe you could check if anything in your page defeats this mechanism or makes it less effective.

In any case, to give more up to the point suggestions, more information about your page would be really great.

By the way, you could have some hints from the crash log that the device store. Check to see if you can find it under Settings:

1. General
2. About
3. Diagnostics & Usage
4. Diagnostics & Usage Data

If it's a memory problem, you should find something like "signal (0)"; not sure if this can only mean "killed due to memory usage", but I usually take this for granted when I found a signal (0).

Otherwise, it might tell you what is wrong...

Hope this helps.
