[ACCEPTED]-terminate called after throwing an instance of 'Poco::SystemException'-exception-handling

anyone knows in what code this uncaught 16 exception is caught?

An uncaught exception 15 is—by definition—not caught anywhere.

If 14 an exception cannot be handled, the C++ exception 13 mechanism will call std::terminate() (see include header 12 <exception>), which will call a customizable termination 11 handler. On your platform, the standard 10 termination handler prints the output of 9 std::exception::what() (which Poco's exceptions inherit from). Unfortunately, the 8 way Poco's exceptions are designed, this 7 will not contain any useful information.

There 6 are multiple ways an exception cannot be 5 handled:

No suitable catch() handler is found and the unwinding mechanism exits main(). You can try wrapping your main() code in try...catch to print the exception's displayText().
A function exits with an exception that does not match its exception specification (... functionname(...) throw(...)). This will call std::unexpected() which in turn will call std::terminate() (by default).
An exception is thrown from within a destructor that is called during the unwinding process of another exception. Never throw exceptions in destructors!
An exception is thrown while trying to create the original exception object. Never throw exceptions in custom exception classes!

When using Poco threads and a thread 4 is terminated by an unhandled exception, Poco 3 will invoke its internal ErrorHandler and the program 2 will not exit, so I doubt that this is a 1 threading issue.

I was getting the same error. I had used 6 a try catch block in the run function of 5 the Poco::Runnable class. I removed the 4 try catch block from this class and used 3 a derivative of Poco::ErrorHandler class 2 to handle the errors. After this I stopped 1 getting this error.
