How can I know how much memory I should allocate to the application stack SL_STACK_SIZE and heap SL_HEAP_SIZE in the sl_memory_config.h file and how much I should allocation to the Micrium OS heap LIB_MEM_CFG_HEAP_SIZE in common_cfg.h file ? I didn't find any tool to check the real...
By analyzing the memory map withpmap, we can identify any unusually large memory segments that may point to memory leaks.Repeatedly checking the same process over time can help us spot if a particular segment, such as the heap or anonymous memory, is continuously growing, indicating a memory l...
You can also increase the maximum memory size but you should keep in mind that heap memory size is a portion of the total memory in a container. As I mentioned above, it needs more spaces for metadata, thread, code cache, e...
2. Understanding Memory in Linux The first thing we need to discuss is what we refer to as “memory usage”. Most applications in Linux use shared libraries. Applications require these libraries to run, but other applications can also use these libraries. This means that it’s not straightforw...

3. Where memory leak $ gcc main.c memleak.c-O1 -g -o main.x $ valgrind --leak-check=full ./main.x ATTENTION: "-O1" to prevent from inline functions by optimization, "-g" to get line number of memory leak functions. In one word,use "DEBUG"flavour instead of "release" while fi...
Buffer overflow/underflow frequently happens when we did something wrong with the array index, no matter the array is heap or stack, no matter you are reading the memory or writing the memory. 1#To get a precise source code line number by valgrind report,2#It's better to build debug vers...

The recommendation is to usejstack. SeeOption 5:jstackLinux script(continuous). JBoss Fuse 6 If you are capturing thread dumps from a child container, note that the process is different to the root container. Be sure to check the process ID (PID) using 'ps' or similar before selecting the...
