B4J Question HTTP TimeOuts

[lip]

B4J Non-UI Program: About 1 in 5 of my HTTP Requests results in a Timeout (after 30 seconds). This has been the case for ever and it happens at every site and on every type of router. There is no sign of the request in any logs on the server so I suspect that the request never leaves the Pi.

In the log below there is mention of ThreadPool. Could it be that my program is running out of threads and therefore not sending the request?

Could it be that my program is running out of threads and therefore not sending the request?

Most probably no. How many concurrent requests do you make?
