Hi,
Our application worked fine on tomcat 8.0.22 on windows server 2003 
server. The tomcat server is restarted daily using a scheduler on 
shutdown.bat (at night) and startup.bat files (in the morning).

We have now upgraded our machine to windows server 2012 64 bit and now 
facing some serious issues like the tomcat remains in hanged stage( not 
responding state.).Once we restart the tomcat server, everything works 
fine.And this happens only once in a day. After the restart of 
tomcat,(manually by double click on shutdown.bat file and startup.bat 
file)  it never repeats.

We have not found any error in all the relevant log files.

We have made the below changes while migration.
        1. java upgrade from 1.7.0_40 to 1.8.0_25
        2.Removed the tomcat-native.dll file from the bin folder.
The configuration of new windows server 2012 is as follows:
        OS Name:               Windows Server 2012-64 bit
        OS Version:            6.2
        java               1.8.0_25 (32 bit)

However, we have observed the below error in the windows event viewer log

"A fatal alert was generated and sent to the remote endpoint. This may 
result in termination of the connection. The TLS protocol defined fatal 
error code is 10. The Windows SChannel error state is 10."

Is this error responsible for the hanging of tomcat server or
Is it due to absence of tomcat-native.dll file ??? or
is there any other reason why the tomcat server goes into hanging state 
???

Any help is greatly appreciated.

Thanks & regards
Deepak kumar
