I am on ATS 6.2.2 version. Can I get some patch for this for 6.2.2.

Thanks

Is this a known issue or fixed in later versions of ATS ?

[SolidWallOfCode]

I think I just saw a local version of this bug which is apparently a problem in the Lua plugin we're investigating.

[SolidWallOfCode]

There are several odd things here. First is that run_NormalStop isn't in TS, presumably it's in a plugin? There is also the proxy_signal_handler on the stack apparently handling signal 15, which is SIGTERM the signal used during a normal TS shutdown. Stack frame 6 is missing, however, so we can't see how the execution went from inside read in glibc to the signal handler, although if it's really a signal that is not overly bizarre.

[pandurangarao]

yes @SolidWallOfCode run_NormalStop is from a plugin. any updates on this one?

[randall]

Updated issue text to code format stack.

If this is still an issue please reopen.
