Public bug reported:
Using apache2 on Ubuntu 8.04 as a reverse proxy. Has been working fine
for the last 6 months. I started recently (last 2 weeks) to enable SSL
for some vhosts. Since then I have randomly apache processes using all
the CPU.
www-data 1332 17641 0 12:38 ? 00:00:00 /usr/sbin/apache2 -k restart
www-data 1333 17641 69 12:38 ? 04:16:50 /usr/sbin/apache2 -k restart
www-data 1336 17641 0 12:38 ? 00:00:18 /usr/sbin/apache2 -k restart
Strace isn't of any help:
yhamon at http-proxy:/var/log$ sudo strace -p 1333
Process 1333 attached - interrupt to quit
read(5, <unfinished ...>
(nothing happens).
I haven't been able to find any information about this on the internet
so far. Please tell me how I can provide more useful data....
