Hi,

i'm trying to make reverse proxy for appwrite (appwrite.io)
but apache is always failing with error

[mpm_event:error] [pid 721274:tid 721274] AH03490: scoreboard is full, not at MaxRequestWorkers.Increase ServerLimit.

i'm using apache version
Server Version: Apache/2.4.61 (Debian) OpenSSL/3.0.13

mpm_event.conf
Code:

StartServers            2
MinSpareThreads         25
MaxSpareThreads         75
ThreadLimit             64
ThreadsPerChild         25
MaxRequestWorkers       150
MaxConnectionsPerChild  0


mpm_worker.conf
Quote:


StartServers 2
MinSpareThreads 25
MaxSpareThreads 75
ThreadLimit 64
ThreadsPerChild 25
MaxRequestWorkers 150
MaxConnectionsPerChild 0

Your ThreadLimit is 64 but MaxSpareThreads 75. The math does not work Wink

Code:

# event MPM
# StartServers: initial number of server processes to start
# MaxClients: maximum number of simultaneous client connections
# MinSpareThreads: minimum number of worker threads which are kept spare
# MaxSpareThreads: maximum number of worker threads which are kept spare
# ThreadsPerChild: constant number of worker threads in each server process
# MaxConnectionsPerChild: maximum number of connections a server process serves
#                         before terminating
<IfModule mpm_event_module>
        StartServers             2
        MaxClients             320
        MinSpareThreads         20
        MaxSpareThreads         40
        ThreadsPerChild         20
        MaxConnectionsPerChild   0
</IfModule>

# worker MPM
# StartServers: initial number of server processes to start
# MaxClients: maximum number of simultaneous client connections
# MinSpareThreads: minimum number of worker threads which are kept spare
# MaxSpareThreads: maximum number of worker threads which are kept spare
# ThreadsPerChild: constant number of worker threads in each server process
# MaxConnectionsPerChild: maximum number of connections a server process serves
#                         before terminating
<IfModule mpm_worker_module>
        StartServers             2
        MaxClients             120
        ThreadsPerChild         20
        MinSpareThreads         20
        MaxSpareThreads        100
        MaxConnectionsPerChild   0
</IfModule>
