Pstack Rpm Download ((LINK))

EDIT: The difference was gdb versions. I used gdb-7.10, and it took about 14 sec to dump stack traces. with gdb 7.0.1, which pstack used, it took 2 sec. Most of time went for gdb-7.10 on loading symbols from our lib, and I couldn't found the appropriate option for -readnever in the new version.
This command displays a stack trace for each process. The pstack commandmust be run by the owner of the process or by root. Youcan use pstack to determine where a process is hung. Theonly option that is allowed with this command is the PID ofthe process that you want to check. See the proc(1) man page.

Then you probably have the x86-64-specific pstack binary, which is less capable than the redhat gdb-based one, as it does not understand posix threaded applications.Ensure that the gdb package is installed, and try the gstack command as a substitution for pstack. gstack is available on Ubuntu, for example. If gstack is not available, a very barebones gstack is provided here:
Attached to this article is a bash script (pstack.sh), which will generate a zip file containing a lot of useful information for the support team in cases where assistance is required troubleshooting a problem in a development, QA/UAT or production environment.
The "pstack movie" generates a stack trace of the MarkLogic process at intervals of 5 seconds for a period of time specified by the user running the script; we generally recommend running this script for one minute (60 seconds)
A running process is wrongly killed when an executable from an NFS drive is running, the executable is deleted, then pstack is called on the active pid. This does not happen when the executable is on a local ext4 drive.
pstack attaches to the active process named by the pid on the command line, and prints out an execution stack trace. If ELF symbols exist in the binary (usually the case unless you have run strip(1)), then symbolic addresses are printed as well.
Hi,
It seems like there is no package for aarch64. Please check if you can download the source code and manually build it. This should be the source code:
GitHub - peadar/pstack: Print stack traces from running processes, or core files. Works properly for x86_64 without frame pointers
I was using pstack on Linux for diagnosing an IO related performance issue. I executed a create table as select statement and ran pstack in a loop for getting stack traces from the running process.
There is no individual SuSE package for pstack/gstack. However, the gdb package contains gstack, so you could optionally install gdb instead, or build pstack/gstack from source. To install the gdb package:
Given thepid of a running process or the full pathof a core file,pstackprints the stack trace for each LWP thread in the process.To obtain symbol information,pstacksearches load modules (executable and shared libraries)in the current directory,$PATH,$LD_LIBRARY_PATH,and$SHLIB_PATH.You can specify the executable pathwith thepid/corepath,separated by a colon(:)character.Ifpstackcannot find a load module, symbol information for framesin that module is not displayed.
I am migrating the old elastix system to new FreePBX Distro (latest 10.13.66) and I am experiencing strange CPU spikes from time to time even though the system is under no load. Spikes sometimes exceed 100% CPU (more than one fully utilized core).
Could you please point me to a direction, how to figure out, why is this happening? I tried ps -LlFm and pstack with no luck so far. I attach top output.
System has currently configured with cca 250 PJSIP endpoints (cca 150 online).
Thank you.
Could you please explain the work around in a little more detail? I can't get success with 10.04.
I've converted and installed /pub/centos/5.4/os/x86_64/CentOS/pstack-1.2-7.2.2.x86_64.rpm
but also needed is a gstack script that I have manually got from gdb-6.8-37.el5. This package also contains gdb so we don't want to overwrite Ubuntu's gdb.
When I run pstack the output is blank. Thanks,
In case it does NOT get into 10.04, could somebody please describe how one can patch & build the related packages in 10.04? I really miss the pstack on Ubuntu, coming from RHEL where it simply works in each release.
I've tried to use the code from here: +source/pstack/1.3.1-1
After building the binary package with "fakeroot debian/rules binary" I have a pstack executable which produces just crap (below example just using nautilus process but it produces similar crap with any running process I've tried):
