Memory Issues with Mysql + 4.0.6

Hi. PHP crashes every time we run a certain batch of reports since we upgraded from 4.0.4pl1 to 4.0.6. The report is ridiculously complex and requires a boat-load of database queries. They ran very well on the previous versions of PHP. Information: --The script tanks after the 34th query, at which point it begins displaying: "Supplied argument is not a valid MySQL result resource." --We have tried the script using: *one connection for the entire script (mysql_pconnect) *recalling mysql_pconnect() before every query without mysql_close() *new connections for every query (mysql_connect...mysql_close) --Same outcome with Mysql versions 3.23.39, 3.23.38 and 3.23.28 --Works perfectly well in PHP 4.04pl1, but not at all 4.06 --Debug log repeatedly contains two messages: FATAL: erealloc(): Unable to allocate 1515870836 bytes [Wed Jul 11 09:12:17 2001] [notice] child pid 16719 exit signal Segmentation fault (11) - --------------------------------------- ./zend_execute.c(358) : Block 0x083FFD78 status: zend_variables.c(62) : Actual location (location was relayed) Beginning: OK (allocated on zend_API.c:379, 10 bytes) End: Overflown (magic=0x2A8FCC82 instead of 0x2A8FCC84) 1 byte(s) overflown - --------------------------------------- I have tried lots of troubleshooting approaches, far too many to mention now. I have also searched the mailing lists and bug reports and have read documents all over the place, all to no avail. If I am being an idiot here, let me know and I'll go away. Thank you for your time and help, Chris Chew
