<br>
Yes, very familiar with the FAQs, we certainly fall into this
category during the single process test:<br>
<br>
"</font></font><font size="-1"><font face="Helvetica, Arial,
sans-serif">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
<em>processes</em>, 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 </font></font><font

</b>we can stream 96+ instances (each with its own environment,
task scheduler & set of event triggers) within a single
process.<br>
<br>
It was strange to see the 'setlocale' being the issue and
wondered if you had any idea or seen this before?<br>
Are we perhaps calling 'setlocale' to often and abusing it
somehow, it's called quite often..?<br>
<br>
Thanks!<br>

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.
