I'm having a strange issue, that I believe has just surfaced since we upgraded to 4.3 - but I'm not 100% sure of that.

We have a custom search that works fine for results sets of up to about 3500 contacts (exact number not yet determined). Above that however, the page custom search page just reloads with all the search parameters missing (as though I just hit refresh on the search page).

I've been trying to find out why for the last week and am completely stumped.

If I put a backtrace on Line 341 of CRM_Core_Selector_Controller and print_r($rows), I can see all of the results, regardless of the number of contacts - so I know at this point, everything is working, but I've been unable to work my way back from here. Below is my backtrace.

Any thoughts? Thanks.
