Bugs. I can see three problems with your program: Your main thread releases the mutex and then uses myEvent without holding the mutex. If another thread grabs the mutex and modifies myEvent, for example by calling trigger_event(), the main thread will be reading/writing the same structure and unpredictable things will happen.; The way you use your condition variable, there is a possibility
Apr 17, 2016 · Objective: View threads of a process on Linux. Threads (also known as Lightweight Processes (LWP)) are created within a program that will have the same “thread group ID” as the program’s PID. They share their address space and system resources with other LWPs within the same process. On Linux/x86-32, the default stack size for a new thread is 2 megabytes. Under the NPTL threading implementation, if the RLIMIT_STACK soft resource limit at the time the program started has any value other than "unlimited", then it determines the default stack size of new threads. A thread's stack size is fixed at the time of thread creation. Only the main thread can dynamically grow its stack. The pthread_attr_setstack(3) function allows an application to set both the size and location of a caller-allocated stack that is to be used by a thread. "On Linux/x86-32, the default stack size for a new thread is 2 megabytes", Unless the RLIMIT_STACK resource limit (ulimit -s) is set: in that case, "it determines the default stack size of new threads". How do I generate a thread dump in JBoss while running on Linux? How do I generate a JBoss stack trace on Linux? How do I redirect output of kill -3 to a file? JBoss has high cpu usage, freezes, hangs, or doesn't release idle threads, how can I get a thread dump to troubleshoot? JMS messages are getting lost, how can I generate a thread dump to investigate? Unable to take thread dump using The child_stack argument specifies the location of the stack used by the child process. Since the child and calling process may share memory, it is not possible for the child process to execute in the same stack as the calling process. When a stack is specified, the thread should also be created PTHREAD_CREATE_JOINABLE. That stack cannot be freed until the pthread_join(3T) call for that thread has returned, because the thread's stack cannot be freed until the thread has terminated. The only reliable way to know if such a thread has terminated is through pthread_join(3T).
Linux Thread Stack Size pthread_attr_setstacksize I am Setting the stack size using pthread_attr_setstacksize. The stack size i set is greter than PTHREAD_STACK_MIN i.e. 16384 bytes for my system. i am setting the stack size to 17408 bytes, and my application crashes due to insufficient stack size. when i set the stack size to 17920 my
Use one of the following procedures to increase the JVM memory allocation and thread stack size by using the Tomcat configuration tool, from the command line or by creating a setenv file. Note You must use the Tomcat configuration tool to configure these settings and restart Tomcat. how do i get stack size of running process? Apr 17, 2011 Xdotool – Window Stack | Linux.org

pthreads(7) - Linux manual page In NPTL, thread syn‐ chronization primitives (mutexes, thread joining, and so on) are implemented using the Linux futex(2) system call. LinuxThreads The notable features of this implementation are the following: - In addition to the main (initial) thread, and the threads that the program creates using pthread_create(3) , the implementation Linux Thread Stack Size pthread_attr_setstacksize
