I developed application running on BB to send email by implement smtp protocol mself. My application setup connection to email server by using socket directly, sometime my application sent out email succeed, but sometime my application got IOException when try to connect to mail server:
guid:0x2C0DBB74C8C46409 time: Thu Jun 11 17:51:33 2009 severity:0 type:2 app:DeviceSide data:net.rim.device.cldc.io.ippp.SocketBaseIOExcep tion: Connection timed out: connect or
guid:0x2C0DBB74C8C46409 time: Thu Jun 11 17:51:33 2009 severity:0 type:2 app:DeviceSide data:java.io.IOException: Failed to transmit

When the exception happend, (RadioInfo.getNetworkService()& RadioInfo.NETWORK_SERVICE_DATA)>0 && !CoverageInfo.isOutOfCoverage() return true which mean the signal is good enough.

Does any one know what cause these exception even when signal is ok? And What's the process that BB setup socket connection from the pointview of BB OS layer?

BTW: When the exception happened, I run BB's Diagnostics Test. After Diagnostic finished, It report"
