Whenever you face this issue in ABAP or JAVA system where your system is not starting up & dumping out by error “unable to create new native thread”.
Please crosscheck the below OS values, this should be set to high/unlimited.
My Suggestion is below –
For Linux – limits or csh -c limits
maxproc – unlimited
descriptors – 65536
stacksize – 32768
after changing these values restart the application server & check.
