I'm seeing this in the error_log file: sh: /which: No such file or directory fairly frequently. Server is centos 5.5 with current centos rpm of apache 2.2.3. The server is running the plesk control panel so there are lots of various include files that make up the apache config. That error seems to occur a random amount of time after the server has been started and then continues to occur maybe every ten or fifteen minutes. I've tried to strace the main httpd and child processes but can't find any execve that involves "which" or sh. I checked for /sh and which in all the domain-level config files and everything under /etc/httpd/ and no matches. Any ideas on how I can track it down? I'm assuming it's outputting that each time a child restarts and reads some config somewhere that it doesn't like.
