some errors from stderr.log FreeBSD x64 8.x

[julian]

system is FreeBSD x64 8.x server running on 'chroot environment'
I want to draw your attention to some errors of stderr.log. Full log https://gist.github.com/anonymous/7ab92bfd69a2270837f7

one more thing, about the log rotation. Server some reason ignores my settings, rotating logs every day, and not in size designation in the settings

You need to check the core file with GDB to find out why PHP crash.
For log rotation, server restart will trigger log rotation if you did not set

that's mean one CGI or php script try to execute a shell script trying to run command "lang", which is not available.
You need to find the script doing that.
