java.lang.OutOfMemoryError "unable to create new native thread" is usually the result of the java process attempting to create more threads than what is allowed at user or system level. For more details, see "[[Linux_Process_Management_Concepts#Maximum_Number_of_Processes_Allowed_on_the_System|maximum number of processes allowed on a system]]" and "[[Linux_Process_Management_Concepts#Maximum_Number_of_Processes_Available_to_a_Single_User|maximum number of processes available to a single user]]".

java.lang.OutOfMemoryError "unable to create new native thread" is usually the result of the java process attempting to create more threads than what is allowed at user or system level. For more details, see "maximum number of processes allowed on a system" and "maximum number of processes available to a single user". To figure out the number of threads, read it over JMX from "", or externally from the O/S-level representation of the Java process, as described here: "".
The number of threads cannot exceed the value returned by ulimit -u. The same value is reported as "max user processes " by ulimit -a. To increase the limit, see:
