Writing logs for zend framework project fails (minapp version fine)

Here's the sample error message I get:

PHP Warning:  file(/var/www/log/2011-03-05T18:01:33/1/http%3A%2F%2Flocalhost%2Fzend%2F1.10.2-project%2Fproject%2Fpublic%2Findex.php%2Fhello%2Fworld/1.log): failed to open stream: No such file or directory in /var/www/include/bench/Siege.php on line 54

Just to note all other projects in all.ini target work fine - it's the only failure.
