SAP – Unable to create new native thread

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.
