java.net.SocketException on calling web service

[Jomy George]

Hi friends,

I have a java server deployed in Tomcat, and this server consumes some webservices hosted in another machine.
We are using SSLSockets for connecting webservice server, and I have their certificate added in my java keystore.

Everything works fine and I can use webservices from my server almost all the time.
But some times i can see 'connection reset' error while trying to access web service.

Can anyone let me know why it is happening, is it related to any certificate issue?
