Has anyone found the answer to why an SSRS report will periodically crash when paging up or down. The error is usually
Sys.WebForms. PageRequestManagerParseErrorException.
Etc
It is annoying enough that the Page Up/Page Down keys can't be used but it adds insult to injury when it crashes like this.
Thanks

This is a simplified description of what's happening. When you run a report with multiple pages, the report server sends you the first page and stores the data for the other report pages in its cache. When you click next page, your client is telling report server "send me the next page of the report you have cached with ID xxxxxxx". But if you take too long to go to the next page, the report server already timed-out the session and drops the cached information. That's the error you are getting.
I haven't been able to find a way to increase the time-out, so the only "solution" I found is to be sure you go through the pages before it times out, or export the report to PDF or other offline format.
