Character lock while fishing

Details:
So far this has happened twice. I was fishing in Abyssea - La Theine at the pond by Crapaudys when my character froze in place. My character stood there motionless, blinking, and it was impossible to cancel out of fishing. The rest of the game continued to run fine: frogs hopped around, buffs wore, time remaining messages still popped up. I had to force DC or kill POL with Task Manager and log back into the game to regain control of my character.

Steps:
Fishing in Abyssea - La Theine. It happens randomly, there doesn't seem to be any way to trigger it. If it matters: Tarutaru with composite fishing rod.

We can offer a few suggestions for the problem you are experiencing:
1. Check to make sure you have properly configured or turned off any of the following: Routers, Proxy Servers, NAT Servers, Internet Connection Sharing services.
2. If you are using any kind of software/hardware Internet Sharing service/device the following ports need INCOMING access to your PC: TCP 1024 - 65535, UDP 53, and 50000 - 65535. Also, check to make sure that the ports mentioned are not blocked by your ISP for INCOMING access. Proper configuration of any of the above items mentioned should be done by following the instructions in the software/hardware manual or calling the manufacturer's technical support.
3. If you are using a router, and have configured that router for port forwarding, temporarily bypass that router and connect directly to the modem.

Please take note of the following:
• Proxy servers, and satellite connections are not supported and do not work correctly with FINAL FANTASY XI.
• Your router may require that you use a PC to configure your network settings. For more information about how to configure your network settings, please refer to the instruction manual that came with your router or contact the manufacturer directly.
• If your Internet Service Provider (ISP) specifies a DNS server, you need to make sure to configure your settings to allow packets to pass through UDP Port 53 as well. For more information, please refer to the instruction manual for your router or the information provided by your ISP.
