Hey folks,

there's been quite a= few issues with the "scoreboard is full, not at MaxRequestWorkers&quo= t; error log message. From what I've found all of them involved some so= rt of heavy traffic. I've been wondering about the root cause for this = but now I have a reverse proxy showing this message right after starting up= - no traffic involved at all.

I'm getting the message for a simple reverse proxy with = about a hundred virtual hosts which is strange because

StartServers = 3
ServerLimit 30
MaxClients 1500
MinSpareThreads 25
MaxSpareThr= eads 75
ThreadsPerChild 50
MaxRequestsPerChild 0

doesn't l= ook like it cannot handle 100 hosts without traffic. The vhosts themselves = look like

<VirtualHost 10.8.17.= 133:80>
=A0=A0=A0=A0=A0=A0=A0 ServerName my_domain_3
=A0=A0=A0=A0=A0=A0=A0 SSLPr= oxyEngine On
=A0=A0=A0=A0=A0=A0=A0 RequestHeader set X-Forwarded-Proto h= ttp

=A0=A0=A0=A0=A0=A0=A0 </Location>
&l= t;/VirtualHost

which is really basic. There is only one v= irtual host with a "real" configuration (setup is part of a scala= bility test).

Again, there is no traffic involved, it's happening righ= t after start up. I checked the processes and the start up is clean, meanin= g there are no old left-overs that might interfere somehow.

Any hints on how to debug this ?
