We have a library checking RTI status. However, if use the library directly as CLI, there is no issue, as long as we import it, our server crashes with the error:

Based on the last line

Mx02:/rti/jenkins/workspace/connextdds/release6.1.1.0/x64Linux2.6gcc4.4.5/src/osapi.1.0/srcC/thread/Thread.c:3630:RTI0x2000005:Received signal SIGSEGV

I am just trying to understand the error what that means, like who send the signal SIGSEGV. Because I didn't find any part of app sending signal SIGSEGV.

Just wonder under what kind of situations, RTI will print this error? Thanks! 😃

Hey @Hongbo-Miao , Can you send me the QoS file you are using the load Connector?

hongbo-miao commented 1 year ago

Thanks @samuelraeburn ! Just add some following up. I wasn't be able to solve the issue at that time directly: as long as I import the library, the existing server will crash at that time. I still don't know the root issue. However, that server is kind of legacy. I ended up creating a new small Flask server and import that package, it works well. 😃
