java.lang.OutOfMemoryError: Unable to Create New Native Thread
catalina.out logs report that Stash is running out of memory:
27-Mar-2015 19:20:00.717 SEVERE [http-nio-57990-exec-5] org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun java.lang.OutOfMemoryError: unable to create new native thread at java.lang.Thread.start0(Native Method) at java.lang.Thread.start(Thread.java:691)
Stash during normal operations will fork Git processes to complete many of it's functions. These Git processes use memory that is available to the system and does not use the memory allocated in the JVM. This error indicates that there was not enough memory for a Git process to start. More information about how much memory Stash requires can be found at Scaling Stash.
Reduce the number of Git hosting operations allowed on the server by lowering the
throttle.resource.scm-hosting in stash-config.properties.
#Default - throttle.resource.scm-hosting=1.5*cpu throttle.resource.scm-hosting=4
Increase the available system memory for the Stash server.
