No. I don't have one. The only possibility I see would be a memory corruption in the network component - it is possible, I didn't write it :-). By reading the source code of the Listen() method, I didn't see anything that could lead to that. But I will check again. That's all I'm asking :) A way to see these kinds of error is running Gambas inside valgrind: $ cd /path/to/my/application/project $ valgrind --tool=memcheck --num-callers=40 --track-origins=yes gbx2 ... And tell me all the messages reported by valgrind during the life of the application. The broken pipe error is irrelevant because I am using a different machine and still have the same issue. I thought you were talking about an error message from your gambas application. The message was in Gambas. A Windows server rebooted. However since then I have changed machines (both the server machine and the workstation) and had the same problem with PUBLIC SUB Socket_Read() or WRITE #Client in PUBLIC SUB Socket_Ready()... until I swapped those two lines of code around. the ServerSocket example stopped working too Yes, it did. I'll keep my eye on the problem. I want to be able to say, I TOLD YOU SO!!! Mind you, it doesn't exactly instil confidence in me to bother getting the application finished. If the information you gave are all exact (rebooting changed nothing, suddenly everything works again), the problem should come from something outside of the operating system. It wasn't working until I the instant I swapped those two lines then, VOILA! It suddenly worked and refused to let me repeat the problem. Anyway, all I wanted was for you to take a look and you've offered to do that so I'm happy. If it happens again I'll let you know if I discover anything. Thanks, your help is appreciated.
