[tracer error] thread XXX delivers a non-SIGSTOP signal #9

Open Xsy41 opened 4 months ago

Xsy41 commented 4 months ago

I modified the MySQL part of this project into MongoDB, including files such as config, src/utils.cpp, src/infrastructure.cpp and src/tracer.cpp, and used YCSB to drive MongoDB for testing. The following error occurs when executing the ./tracer command: [tracer][error] thread 2129 delivers a non-SIGSTOP signal [tracer][error] tracee exits normally, exit num = 1

The full console output is as follows: error.txt

Hope to get your help, thank you!

After BOLT finished, I found that the mongod in the background was gone, and the ps aux command was also gone.
