christophe wedeux	Monday 28 April 2008 1:43:32 am Hi, i have a batch that use lot of object and i have this message "error canary mismatch on efree() - heap overflow or double efree detected" . Anyone know that and find the solution? I use a 3.9.1 on FreeBSD linux with PHP 4.4.7 and Mysql 2.11.0
Steven E. Bailey	Monday 28 April 2008 4:01:04 am You are using a apache version with the suhosin patch? I had this error message while running remove drafts - lots of objects, etc. I managed to work around it by having the program loop and do 100 objects at a time. I think it's related to the suhosin patch...
