I experience a strange error which is filling up var/system.log:
2016-01-18T17:04:25+00:00 ERR (3): Notice: Undefined offset: 22 in /chroot/home/www/files/html/app/code/core/Mage/Catalog/Model/Layer/Filter/Price/Algorithm.php on line 366 2016-01-18T17:04:25+00:00 ERR (3): Notice: Undefined offset: 0 in /chroot/home/www/files/html/app/code/core/Mage/Catalog/Model/Layer/Filter/Price/Algorithm.php on line 368 2016-01-18T17:04:25+00:00 ERR (3): Notice: Undefined offset: -1 in /chroot/home/www/files/html/app/code/core/Mage/Catalog/Model/Layer/Filter/Price/Algorithm.php on line 384 2016-01-18T17:04:25+00:00 ERR (3): Notice: Undefined offset: -1 in /chroot/home/www/files/html/app/code/core/Mage/Catalog/Model/Layer/Filter/Price/Algorithm.php on line 395 2016-01-18T17:04:26+00:00 ERR (3): Notice: Undefined offset: 20 in /chroot/home/www/files/html/app/code/core/Mage/Catalog/Model/Layer/Filter/Price/Algorithm.php on line 366
Unfortunately I had no luck debugging it. I could not narrow down the issue nor find any related overwrites.
The site is running on Magento ver. 1.9.2.0 and PHP Version => 5.3.24
Any ideas what could cause the issue?
