The problem does not show up with public access (ie no LDAP > validation). I'm not familiar with apache internals, nor LDAP, but I can try to help begin diagnosis.
Could you provide a strace of the process when it is in that state? (strace -p <pid>)? Maybe also a strace of the process beginning before it is in that state, and ending sometime after it has gone into that state. Maybe also a gdb backtrace? (LD_LIBRARY_PATH=/usr/lib/debug gdb -p <pid>); you should first install the package libc6-dbg, if possible. If not, then don't set LD_LIBRARY_PATH. It will at least tell us if the stack is still sane, or if there has been memory corruption. Depending on the result, I (or someone else) may request that you do (or do not) compile some software with debugging enabled, which might give the backtrace much more info.
