Tomcat7 memory usage - Error 503 Service not available! #587

What steps will reproduce the problem?

During normal operation, PWM stop responding after sometime with a 503 Service 
unavailable error message.

I put this in the general discussion but because we are in a big trouble I am 
posting it here also. I am sorry if it doesn't belong here. 

We are using PWM with 64 bit eDir 888 on a 64 bit Windows 2008 R2 server plus 
Tomcat7 and Apache 2.2.
We are running both PWM 1.7.1 and PWM 1.6.4.

The problem is that Tomcat is using huge amount of memory and there isn't crazy 
load on the server either. It is using approx 600mb all the times and in times 
it exceeds 1g and that is the time when PWM stop responding. During this time, 
Tomcat is still running and "processing" and hence we don't have any error 
messages in the Tomcat log.
Restarting Tomcat doesn't help resolve the problem and we have to restart the 
server. Once the server is restarted, it works for a while and then the same 
happens again.

Can anyone please suggest me anything? I will be extremely thankful. 

Thanks
