Thanks for any help.

Is there any other exception logged somewhere?
Maybe your system is not able to handle 1000 threads and you have core
jvm exceptions for that.
You should keep the number of max connections allowed and threads to
something your hardware/OS is able to manage.
max-connections should be limited, threads should be limited.
If you don't limit anything than the hardware or the OS will limit you
sometimes.
