you encountered the "reached maxclients" condition with MaxClients=1500...

whether that is expected is up to your app and the traffic

if the app hangs or takes a long time to respond, you could reach the
maxclients limit regardless

if the app is responding appropriately and your machine has capacity,
increase maxclients

you set MaxSpareThreads to 100; that's 2 * your ThreadsPerChild

don't worry about StartServers

notice that your MinSpareThreads and MaxSpareThreads values and the
difference between them are a small percentage of MaxClients; if load
changes by a very small percentage, child processes will be terminated
or started

perhaps this preso would help:
