Valgrind's massif tool will not profile my application

问题 I am developing a statically-linked 64-bit C++ application on 64-bit CentOS 5.8 using the standard gcc 4.4 packages from the CentOS repositories. It appears to be using more memory than I expected, so I tried using massif to profile the memory usage. I have compiled with debug information and then run valgrind --tool=massif ./MyProg from the directory where MyProg resides. It never produces any results other than the following massif.out.XXXX example. desc: (none) cmd: ./MyProg time_unit: i #

Why doesn't valgrind massif report any function names or code references?

问题 I have a program that is unexpectedly using a large amount of heap (about 3GB). I ran it through valgrind memcheck which reported no leaks, claiming that all the heap memory is still reachable. So I rebuilt all my libraries with debug options, and ran the prog through valgrind massif. I am using Valgrind-3.8.1 which I just downloaded and built on my box today. The command line was: valgrind --tool=massif myprog Valgrind produced no errors or warnings. The resulting output file is reporting

How do I find why the virtual memory foot print continuously grows with this daemon?

问题 I created a daemon which I use as a proxy to the Cassandra database. I call it snapdbproxy as it proxies my CQL commands from my other servers and tools. Whenever I access that tool, it creates a new thread, manages various CQL commands, and then I cleanly exit the thread once the connection is lost. Looking at the memory footprint, it grows really fast (the most active systems quickly reach Gb of virtual memory and that makes use of some swap memory which grows constantly.) On startup, it is

问题 I'm using Valgrind 3.3.1 with the Massif tool to profile the heap of a C++ application, and I'm wondering if there is a graphical tool to examine the textual outputfile file. Thanks for any suggestion. 回答1: For anyone else who is still interested in graphical output of Massif from Valgrind please consider massif-visualizer, it is beautiful. You can find the project page at KDE-Apps. For Ubuntu you should build massif-visualizer from source or install package from Kubuntu-ppa repo: add-apt

localtime_r consuming some memory before program exit

问题 I use valgrind's massif to track memory usage at the last stage before program exit and found js::DateTimeInfo::updateTimeZoneAdjustment() (DateTime.cpp:19) which is calling localtime_r and consuming some memory. 16 ComputeLocalTime(time_t local, struct tm *ptm) 17 { 18 #ifdef HAVE_LOCALTIME_R 19 return localtime_r(&local, ptm); 20 #else 21 struct tm *otm = localtime(&local); 22 if (!otm) ms_print of last snapshot from valgrind's massif 427711 -------------------------------------------------

问题 I am attempting to build massif-visualizer on CentOS 7. Unfortunately I'm having to try to guess at dependencies as they are not all listed in the INSTALL file. So far: yum install git yum install kdelibs-devel extra-cmake-modules \ qt5-qtsvg-devel qt5-qtxmlpatterns-devel \ kf5-kparts-devel kf5-karchive-devel git clone https://github.com/KDE/massif-visualizer cd massif-visualizer mkdir build (cd build && cmake .. && make && make install) Those Qt5 and KF5 packages were added to the yum
