Maximum connection reached exception in TCP Gateway

Hi,

We are triggering outbound data from PI to Client Target system, in between we have an another server, where TCP Gateway Tool runs and data flows happens from PI->Gateway->Client Target server.

Message flow is normal and suddenly we are getting an 'java.net.socketException: No buffer space availble' in TCP Gateway . When i restart the gateway, again message flow is getting normal.

java.net.SocketException: No buffer space available (maximum connections reached?): connect at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(Unknown Source) at java.net.PlainSocketImpl.connectToAddress(Unknown Source) at java.net.PlainSocketImpl.connect(Unknown Source) at java.net.SocksSocketImpl.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at java.net.Socket.<init>(Unknown Source) at java.net.Socket.<init>(Unknown Source) at com.sap.aii.axis.utils.TCPGateway$Connection.run(TCPGateway.java:878)

Kindly advice on the issue.
