I am still not clear on the split pipe problem. I read the knowledgebase article, the sticky thread on the connections, and some other related articles.

Based on these, since Network Diagnostic Tool tries to make BES, BIS, Wi-Fi, etc. connections, does this mean this tool can cause split pipe problem? if this happens, then would this tool be useless for that device?

Are you having the "split pipe" issue, or are you just asking for informational purposes?

The quick answer is that AFAIK, the NetworkDiagnostic tool is unlikely to run on a device that is old enough to exhibit the split-pipe issue.

Maybe Mr. Kirkup (the "father of split-pipe") can provide some advice.

I am asking for informational purposes. 

What do you mean by old device? The knowledge base article does not mention anything about software version or the model number. Could you explain?

Support - The application has attempted to open a connection to a location inside the firewall and outside the firewall.

That article was last updated Feb. 2005. In BlackBerry time, that's someplace around the Bronze Age.

I'm fairly certain that this issue was resolved sometime around 4.1 or 4.2 - we haven't had a "split pipe" support incident in years.

Maybe somebody else has a different experience.

Hmmm. My understanding from the sticky article by peter_strange was that this is a fairly general problem.

Any experiences objecting to RexDoug's comment? So if I am a developer targeting, for instance 4.3, then does this mean there is nothing I need to worry about split pipe issue and I can freely try BES and then other transport types in my application?

split-pipe is alive and well, curve OS 4.5. having much difficulty trying to solve.

[RexDoug]

What are the circumstances precipitating the issue?

[aleksandr]

Please have a look at my other forum entry where I describe a my theories that it seems to be related to HTTP and a file connection. I am still trying to sort out where the issue is comming from.

Can confirm we see it in 4.5 with our common connection class.  Not tried it in anything after that.  The issue reported in the other thread with split-pipe and a file connection, was seen in 4.6. 

[aleksandr]

For the issue with the file connection: do you think it was a matter of having the file connection open at the same time that HTTP was used OR did it happen if the app ever created a file connection and used HTTP?

thanks,
