Issue/Introduction

The ProxySG may return a tcp_error - "Address already in use" exception page when it runs out of usable TCP ports.

Resolution

To increase the usable TCP port range, use the following commands :

ProxySG#configure terminal
ProxySG#(config)tcp-ip inet-lowport 16384 
ProxySG#(config)tcp-ip tcp-fast-finwait2-recycle enable
ProxySG#(config)tcp-ip tcp-randomize-port disable
ProxySG#(config)exit

If these commands are not available, you may need to upgrade your SGOS to the latest SGOS 5.4, 5.5, or 6.2 GA versions respectively.
