Unsure of when it started, but dmesg just gives line after line of:
pid 7913 (httpd), uid 65534: exited on signal 11
pid 7912 (httpd), uid 65534: exited on signal 11
pid 7910 (httpd), uid 65534: exited on signal 11
pid 7906 (httpd), uid 65534: exited on signal 11
Not thinking it was related until ppl brought up the 'daemon dying'
thread, I didn't mention it previously, but I killed off httpd and
restarted it, which stop'd the scrolling messages...but has not stop'd
thee 'junk pointer' messages...
I dread having to reboot it, but its looking like I may just have to do
that ;(
