Hello,
I seem to have the same problem as the person in the link below
[RCU] canary mismatch on erealloc() - heap overflow detected (http://www.mail-archive.com/
[email protected]/msg01307.html)
[Wed Apr 22 10:20:23 2009] [error] ALERT - canary mismatch on erealloc() - heap overflow detected (attacker 'xxx.xxx.xxx.xxx', file '/webroot/roundcube/public/program/lib/PEAR.php', line 275)I am also running FreeBSD but with Apache1.3 and PHP5.2.8.
I also seem to have 7 httpd-processes 'hanging' in Gracefully finishing. and slurping up 1.00 CPU per process... I am now running at 7.00 full... After a restart of the webserver they are gone ofcourse. But after a day or two there are new hanging processes in the list
There are 7 entries of the given error message in my log file.
[EDIT
The processes that are hanging are without any information

EDIT]
This must be roundcube related as that's the only script i have running on that server.
Is there any info on this issue i can use to solve it?
Is this a known bug?
Any info i can use to make progress on this issue would be greatly appreciated!
