Question

I have a website running with Pyrocms & CodeIgniter.

My config is the following:
Debian: 5.0.9
Apache: 2.2.9
MySQL: 5.0.51
PHP: 5.2.6-1

I’m facing the following problem:

I receive POST requests to insert messages in my database.
Sometimes the frequency of db insert is up to 100 messages / seconds

Database engine used : innoDD

After a moment I get a white page when i try to reach the homepage or any modules except the admin.

http://www.project.com is giving HTTP status 200 but page is blank
same for http://www.project.com/mycontroller is giving HTTP status 200 but page is blank
admin is working fine

In my log files i have following errors :
ERROR – 2011-11-18 15:04:28 –> Severity: Notice –> iconv() [function.iconv]: Detected an illegal character in input string /home/project/system/codeigniter/core/Utf8.php 89

For the moment i do a dump of my db every 30 minutes and rollback to the last working db when the plateform is crashing.

I have made some tests on my database with mysqlcheck but everything seems to be ok in the db.

Thank you for your help.

PHP is probably choking on some characters when converting with iconv. try adding “//IGNORE” to you second argument so it looks something like that

iconv("UTF-8", "ISO-8859-1//IGNORE", $text);
