Connection refused : SocketException

[kpanchalwk]

I'm consuming nClam by initializing ClamClient with localhost and default port as singleton via dependency injection. I'm facing "SocketException" exception when increases the no of requests to the service. Is there any limitation on no of parallel requests that ClamAV can handle or any thought on this?
