I only have a minute because I'm trying to get my server back up!
It went down about an hour ago and the ony clue I see is in the apache log:
DBI connect('database=dbispconfig;host=localhost:3306','ispconfig',...) failed: Too many connections at /usr/local/ispconfig/server/scripts/vlogger line 255
DBI Error: at /usr/local/ispconfig/server/scripts/vlogger line 255.
piped log program ' /usr/local/ispconfig/server/scripts/vlogger -s access.log -t "%Y%m%d-access.log" -d "/etc/vlogger-dbi.conf" /var/log/ispconfig/httpd' failed unexpectedly
This shows up over and over.
