apache logs and stats problem

I upgraded yesterday from 2.2.8 to 2.2.10 and since that time I have had problems.

I finished the upgrade at about 15:00 yesterday but the access logs for apache2 are odd. (debain 3.1 perfect setup)

There are no entries for any site after midnight on 25th and one site doesn't have anything since the upgrade at all, in fact there is no file web.log in

/home/www/web19/log/2007/02

also the apache2 logs in /var/log/apache 2 are as follows:

error.log

unable to start piped log program '/root/ispconfig/cronolog --symlink=/var/log/httpd/ispconfig_access_log /var/log/httpd/ispconfig_access_log_%Y_%m_%d': No such file o

access.log

xx.xx.xx.xx - - [25/Feb/2007:14:07:38 +0000] "\x80=\x01\x03" 302 407 "-" "-"

Any thoughts?

P.S This line appears quite a lot in /var/log/syslog

Feb 26 07:39:28 mail syslog-ng[7727]: STATS: dropped 0

and there is no mention of apache in there!!

Thanks

Ben
