http generated core files

[sirjune]

I have a Solaris 10 box and http had generated a lot of core files on /var/core. core_hostname_http_numbers_numbers..

my swap had been used up to the last byte and i had to stop Apache and restart it again to put back the server online. How do i read these core files and know the cause why http is generating them and http eating up my swap?

thanks,
Sir June
