Is there any way to diagnose Unmanaged memory leak ? I am using .NET 5.0 Console App with NETCode (barcode) library. The program it self is simple it calls barcode library & creates a base64string from Image 5000 times, I am using ‘using blocks’ therefore disposing is also being handled. On windows this program consumes 15-25 MB (doesn’t go above

What is using so much memory on an idle linux server? Comparing output of “htop” and “ps aux”
I am trying to understand and compare the output I see from htop (sorted by mem%) and “ps aux –sort=-%mem | grep query.jar” and determine why 24.2G out of 32.3G is in use on an idle server. The ps command shows a single parent (not child process I assume): Whereas htop shows PID 6790 as well as many other PIDs
Which Valgrind tool and option to use for investigation of RAM allocation for each function?
I have never used Valgrind, but I think this tool can help me with my question. I would be grateful for any help. In my R code, I use the MixedModels Julia package. I integrate Julia in R using the JuliaCall package. I work with very large datasets (~1 GB, ~4×10^6 observations) and at the modeling step (mixed models) a
How do I find a system memory leak in linux?
I’ve got a monolithic piece of software, a game on a basic linux kernel, that seems to leak memory in swap space. The memory usage of the process itself is reported as constant over a day or so but the free memory on the system is consistently decreasing until there is no more physical ram space. There is no other
valgrind Address 0x421688c is 0 bytes after a block of size 4 alloc’d for linked list having integer data
Although there were multiple threads related to valgrind Address 0x421688c is 0 bytes after a block of size 4 alloc’d kind of questions, but all were expressed with either strlen, or ” related issues and I understand them. I am having with linked list insertion dealing with integers. I did insertion, deletion steps and get summary(showing last few lines of
‘top’ shows Java program using more memory than Java profiler shows
What are the possible causes for when the Linux top command shows a Java process is using 14GBs of memory while Java profiling shows only 2GBs being used? Answer That means that your JVM / Java application is using off-heap memory. Lots of it. It could be memory-mapped files. It could be native libraries: unlikely … for that much memory.
Socket Server Memory usage goes up, becomes unresponsive
I have the following socket server code for Linux using Pthreads. If I start stress testing this with: The memory increases to about 270MB then the server becomes unresponsive: On ARMv7 architecture this takes a shorter time. If I stop the requests with the for loop, the memory does not get freed up, meaning that this server would sooner or
Mem alloced via mmap without munmap will cause leak after process exits or terminals
there is the code about alloc mem via mmap void *ret = mmap(NULL, 4 * 1024, PROT_READ | PROT_WRITE, MAP_PRIVATE | MAP_ANON, -1, 0); when process exits normally, the memory will be return to os ? Answer According to the man and under unmap: The region is also automatically unmapped when the process is terminated. Which sounds very reasonable as
