In Pega 8 , We have removed SMA and introduced Admin studio . There are lot of backed jobs running for this. SO it require more threads to run this backed activities. We already check with our SMA . It is not sufficient with the default threadpool size , Because of this we are observing lot of Pega0104 alert.
As suggested please increase the thread pool size with the below prconfig setup .
<env name="agent/threadpoolsize" value="XX"/>
