Hi,

With this code, the ConnectionTimedOut exception is never handled:

| socket data | socket := Socket newUDP. socket setPort: 51284. socket waitForDataFor: 5. data := ByteArray new: 100. [[socket receiveUDPDataInto: data] on: Error do: ['Catched error, closing socket' crLog. socket closeAndDestroy]] ensure: [ 'Closing socket' crLog. socket closeAndDestroy]

Any reason it does not work?

In Pharo I see several examples using ifCurtailed.

#receiveUDPDataInto: returns immediately, possibly with zero bytes read. It is #waitForDataFor: that signals the ConnectionTimedOut. Move that expression into the inner block. Sven
