Hi Ross,
Yes, very familiar with the FAQs, we certainly fall into this category
during the single process test:
"Another possible way to access the code from multiple threads is to
have each thread use its own "UsageEnvironment" and "TaskScheduler"
objects, and thus its own event loop. The objects created by each thread
(i.e., using its own "UsageEnvironment") must not interact (except via
global variables). Such a configuration is not recommended, however;
instead, it is safer to structure such an application as multiple
/processes/, not multiple threads. "
Not using any static variables, all code remains class based our side.
Each RTSPClient has its own thread for the event loop and we invoke on
another dedicated thread ourside for invoking response handlers. Simply
put, if we define *LOCALE_NOT_USED *we can stream 96+ instances (each
with its own environment, task scheduler & set of event triggers) within
a single process.
It was strange to see the 'setlocale' being the issue and wondered if
you had any idea or seen this before?
Are we perhaps calling 'setlocale' to often and abusing it somehow, it's
called quite often..?
Thanks!

I didn’t really follow this. However, I was disturbed by the following:
By default the NEWLOCALE_NOT_USED is defined and works great when we run up
many streaming windows all in separate process's.
If we use a single process (less memory consumed by NVIDIA graphics) we see an
access violation
I hope you are not running more than one thread in "a single process” - because
this is not allowed. LIVE555 code (within a single process) is meant to run as a
single thread, using a (single-threaded) event loop for concurrency. See
