I seem to have hit a limit in the number of worker threads that can be started
on nxlog.
If I configure enough inputs to warrant more than 15, nxlog crashes with an
access violation (see below).
NOTE: I'm running nxlog-ce-2.4.1054 on windows - haven't verified if same is
true on unix.
I've been able to work around this bug by explicitly specifying (limiting) the
number of threads in my conf:
Threads 15
Unfortunately I'm unable to login to sourceforge to log a bug, but wanted to
put this onto the list since it took me all day to track it down.
Cheers,
Shawn
Here is the DEBUG output when nxlog crashes:

If I take any one of my inputs/routes away, or, if I manually specify 15
threads, then everything starts fine:
