Tomcat8.0.33 AJP connector is hanging

[Venkata Reddy P <Ve...@trianz.com>]

Hi,

I have override the AjpProtocol to inject ssl communication by providing SSLImplementation  which is working well with the http connections(PocHttp11Protocol) for the same SSLImplementation. But some reason ajp connections are failing.

1)      All the connections to the AJP-BIO is hanging on  method (at java.net.DualStackPlainSocketImpl.accept0(Native Method)).

Could you please give me any clue what I am doing wrong?


2)      AJP SSL communication also failing. When I generate the ssl logs at server side,  I could see the below error.
SSL error from server end:-
ajp-bio-xx.x.xx.xx-50000-exec-1, RECV TLSv1.2 ALERT:  fatal, bad_record_mac
%% Invalidated:  [Session-17, TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384]
ajp-bio- xx.x.xx.xx -50000-exec-1, called closeSocket()
ajp-bio- xx.x.xx.xx -50000-exec-1, handling exception: javax.net.ssl.SSLException: Received fatal alert: bad_record_mac
ajp-bio- xx.x.xx.xx -50000-exec-1, called close()
ajp-bio- xx.x.xx.xx -50000-exec-1, called closeInternal(true)

Could you please give me any clue?   The same SSLImplementation was working well in tomcat6.0.x version.



3)      Here my ajp maxThreads defined as 150  but  I could see only below 3 threads.
<Connector port="50000" maxThreads="150" tomcatAuthentication="false"
               address="XX.X.XX.XX" enableLookups="false" protocol=" com.trianz.poc.tomcat8..PocAjpProtocol" />


Am I missing any attributes in tomcat8?
