Error: Data file is corrupted

nadoo — Mon, 09 May 2022 08:43:51 GMT

I am running vtune 2022.1 on a centos7 machine to analyze the hotspot consumption of a business process. When I run the hotspot collection, the resulting data file is corrupted. This error occurs many times

Some background info:

$ uname -a
Linux tlinux2-2 3.10.107-1-tlinux2_kvm_guest-0049 #1 SMP Tue Jul 30 23:46:29 CST 2019 x86_64 x86_64 x86_64 GNU/Linux

$ vtune --version
Intel(R) VTune(TM) Profiler 2022.1.0 (build 621966) Command Line Tool

Here is the error:

$ date && vtune -run-pass-thru=--no-altstack -collect hotspots -duration 300 -target-pid 4110 && date

I found that every time this kind of data corruption error occurs, the business process disappears abnormally, by adding an audit rule that audits the kill operation in the audit service:

$ auditctl -a exit,always -F arch=b64 -S kill -S tkill -S tgkill -F a1!=0 -k my_audit_event

Part of the audit log:

$ ausearch -k my_audit_event |grep opid=4110 -C 5 |more

Through the audit log, I found that the business process exited due to receiving a signal. This process '~/intel/oneapi/vtune/2022.1.0/bin64/pinbin' has many system calls, and system call 234 corresponds to #define __NR_tgkill 234 (reference: cat /usr/include/asm/unistd_64.h),

What is the process of 'pinbin', and why does it issue the command to kill the business process?

Hi,

Thank you for posting in the Intel Communities.

As you mentioned, you are using Vtune 2022.1 on Centos 7, which is deprecated in this release, Intel® OneAPI 2022.1, and will be removed in a future release. So, could you please try it on a supported operating system and let us know?

Thanks,

Hi, according to the list of supported operating systems, centos7.2 is supported.

$ cat /etc/centos-release 
CentOS Linux release 7.2 (Final)

Thanks,

Nadoo

Hi,

We informed our team to make changes to the documentation to avoid confusion. We tried to run a 5-minute application with the command you provided and it was running fine without any issues on Centos 7, and it took a few seconds to analyze the data. Please go through the attached screen shots.

Details :

OS : Linux (Centos7 distribution)

VTune Version: 2022.1

Could you please answer the following questions:

1. Are you trying to run your application inside of a VM?

2. Please, can you share the exact steps you followed and a sample reproducer (a sample application that is similar to the application you are trying to analyze)?

Thanks,

Jaideep
