Upload pictures causes core dumps in wp-admin folder

Hi

I have a problem with uploading pictures using drag and drop from a local file folder where core dumps are generated. When I analyse the core dump using ‘strings <coredump>’ it indicates the active php file is ‘async-upload.php’.

The basic php configuration information is:

System Linux ******* 2.6.18-348.1.1.el5xen #1 SMP Tue Jan 22 17:00:37 EST 2013 x86_64

I have looked through the history of support tickets for core dumps, but I cannot find any recent ones. Could someone advise where to look for the configuration problem.
