Hangs...

[joecar]

SlickEdit Pro 2019 (v24.0.0.8 64-bit)

Sometimes SlickEdit hangs, with cursor spinning, indefinitely... I'm not sure what happened leading up to this.

[Dennis]

In this case, can the editor be interrupted if you press Ctrl+Alt+Shift+F2 or Ctrl+Alt+Shift+F9 ?

Note, on MacOS, the combination to interrupt the interpreter is Ctrl+Option+Command+(s or t)

If so, could you post the resulting Slick-C stack ?

[joecar]

Ok, will do when it happens again.

[joecar]

Hang occured again, I did Ctrl+Alt+Shift+F9, editor interrupted with the following:

Could you attach your <config dir>/logs/stack.log.  It looks like these stacks were truncated.

FYI,

I have been seeing SE v24.0.0.8 hang / freeze with Ubuntu 14.04 and Ubuntu 18.04 as well. I have a case file open, but did post a screen snapshot, gdb stack trace and maps file.

Just saw this via my Ubuntu 16.04.6.


Totally locked up an unresponsive to keys mentioned.   I did capture the following via a gdb and strace.  htop show one CPU core running at 100% for the vs_exe.

Yeah, that looks like the same stack reported by @Taeguk.   We're investigating it.  Thanks for posting that.

[Dennis]

Just an FYI, you need to hold Ctrl+Alt+Shift+F9 down for a few seconds in general to force the interrupt.

I'll try that again if I encounter it again.    How long is "a few seconds?"

[joecar]

Could you attach your <config dir>/logs/stack.log.  It looks like these stacks were truncated.

See attached.

I'm running on Win10.

[joecar]

What is the difference between Ctrl+Alt+Shift+F2 and Ctrl+Alt+Shift+F9...?

[patrick]

@b if it doesn't respond after holding it down for 10 seconds, I'd say it's not going to.
Also, can we get your user.cfg.xml file from your configuration directory?

I also seen a hang regularly (enough that I now Ctrl-S every couple seconds...). I've tried the Ctrl-Alt-Shift-F2 and Ctrl-Alt-Shift-F9 and have not been able to recover from it either.
