On 6/20 we hit our thread max which caused the environment to go down. An Atlassian support rep recommended increasing the max threads to 120. This seemed to be a band-aid because we are approaching max again.
Error in logs:

The applied fix:

2) Open the server.xml file in the installation directory/conf and change the following:
This morning, a Confluence process is currently consuming over 75% of the overall CPU. I am not sure if this is related. We plan to restart the Confluence service at 8PM tonight as long as the CPU stays around 80%.
Anyone have any other suggestions to resolve high CPU/load/thread issues? If not, I will open another case.
hi, we have the same issue and allready have set the values
<Connector SSLEnabled="true" acceptCount="100" port="443" clientAuth="false"
connectionTimeout="20000" disableUploadTimeout="true" enableLookups="false" keyAlias="1"
maxHttpHeaderSize="8192" maxSpareThreads="75" maxThreads="150" minSpareThreads="25"
protocol="org.apache.coyote.http11.Http11Protocol" scheme="https" secure="true"
sslProtocol="TLSv1.2" useBodyEncodingForURI="true" sslEnabledProtocols="TLSv1.2"
but the cpu load still climb to 99% of the java process...
do you have a idea?
