clion cpu 100% and more on ubuntu

Hey guys,

I see a strange pattern , even that clion is
not "doing" any comilation or cache building
any heavy operation I do constanetly see
that the cpu is 100% and more.

Any idea ?

Thanks
Roman.

Could you please provide a cpu snapshot and file an issue in our tracker? We'll investigate it.

I have tried to start
clion with that option
and it doesn't start:

-agentlib:yjpagent

any othere ideas how to
profile for you this cpu
problem ?

For the 64-bit JVMs -agentlib:yjpagent64 option needs to be used instead or the IDE will not start.

apparently it was starring by default all the time.
here is the snapshot during it the cpu was ~300%,

Cheers.

thanks! We'll investigate the case.
I've placed your description and snapshot to this issue: http://youtrack.jetbrains.com/issue/CPP-1080

I am having the same issue. The CPU utilization goes above 100% and the system stops responding — this is super frustrating. I am running it on an Alienware 17 R4. Please let me know if there’s a fix for this. Thanks

Hi, Ali.

Sorry for the inconvenience! Could you please capture a CPU snapshot and send it to clion-support at jetbrains.com? It would help us to investigate the issue.

Me too having the same issue. On Ubuntu 16.04 with KDE.

Enabling power-saving mode solves the issue, but I still want code insight.

After following that "CPU snapshot" guide, only "Capture Memory Screenshot" is available, like in the attached picture

Proposal, have you enabled the Profiler Agent as described in the "Enabling Profiler Agent" section?

Yes I had.

It only involves adding that "-agentlib:yjpagent64=delay=10000,probe_disable=*" to my vmoptions right?

At CLion startup, it complains about "Could not find agent library yjpagent64 on the library path, with error: libyjpagent64.so: cannot
open shared object file: No such file or directory"

So I use "LD_LIBRARY_PATH" to https://www.yourkit.com/java/profiler/download/ binary file for Linux x86-64, and renamed that "libyjpagent.so" "libyjpagent64.so" and it started, but it only shows the menu above.

I'm using CLion 173.4674.29 downloaded from Toolbox on Ubuntu 16.04 for x86-64.

Erica, for the 64-bit JVMs on Linux the line in VM Options should be

-agentlib:yjpagent-linux64=delay=10000,probe_disable=*

For 32-bit:

-agentlib:yjpagent-linux=delay=10000,probe_disable=*

The libyjpagent-linux.so and libyjpagent-linux64.so libraries should be located in the bin folder of CLion.

Sorry for the inconvenience.

I have captured the CPU Profiling data. How to attach the snapshot file?

Additional info: This only happens on CLion's code inspection on a single file in my project. It stuck at 7% in "Syntax analysis". The file is a C++ file with about 350 lines. It's a small project either, with only about 1000 SLOC in total, spread across 20 files.

Erica, you can send it to clion-support at jetbrains.com
