Show pausing worker threads in preparation for power spike about stressapptest HOT 13 OPEN

I'm running at CentOS6.5 x64.

Can you specify exactly the failure mode? Does the program hang, or exit 
unexpectedly, or does the system hang, or something else? Also, can you include 
the full log? 

This pause is intended to find issues related to sudden change of load and 
power usage.

The program not hang, not exit and my system not hang.
But, the program keep running over 28800 sec and no any result about pass or 
fail.

Did it keep printing stuff? It shoudl print a note every 10 seconds or so. 
What happens if you press ctrl-C?

NO, after show "pausing worker threads in preparation for power spike", then it 
will not printing stuff.
If I press ctrl-C, it have no response. 
If I press ctrl-Z, it will exit. But I have checked my system CPU, Memory 
loading, it's still keep running...

Hi, sorry for bother you.
Do you have any comment?
Thank you

Can you build with debug and run under gdb? When stressapptest is stuck, then 
break and see where it is stuck?

I'm not able to reproduce this on Ubuntu 64bit.

Also, just to get it running, you may add 
--pause_delay 100000
which will not run any pause within the 28000s run.

Hi, how to build with debug and run under gdb? Thanks

Hi, do you have any updates? thank you

# This adds debug symbols to the build:
CXXFLAGS+=" -g" ./configure
make

# Run under gdb
gdb ./src/stressapptest
(gdb) r -M 200 -s 200 --pause_delay 10

# Break at the problem occurance
^C when stressapptest appears to be stuck

# Check thread state
(gdb) info threads
(gdb) thread apply all bt

Then paste the result here.

Hi, thanks for your help.
About Log, please refer to the attachment file.

It looks like the "thread apply all bt" command didn't get run.. Can you wait 
until "info threads" is complete and then run the other command? 

It does appear that stressapptest is stuck.
