Reopening since it happens on 5.5.0.
Do you have a sample test case to check it?
Not in front of my PC,
But I can describe what I did as it's pretty simple. I have a tomcat webapp that launches jython through JSR223 ( but it also happened when I called Jython directly).

Hi, I have tried it without the embedded tomcat server. It seems to be working. I wonder what tomcat is doing that may cause this disconnect.
Hi Fabio, We've just noticed another strange thing. Running our webapp with Jetty instead of Tomcat works flawlessly. Can you think of a something in pydevd that may conflict with Tomcat? Maybe the problem is a pure Tomcat configuration issue.
Thanks in Advance.
Unfortunately no... my guess is that for some reason the tracing calls (from sys.settrace) are not being called...
The usual culprits are:
Thanks Fabio. We only have a single process that calls settrace. Running Wireshark we see a tcp.fin entry originating from the jython side, but I don't know how to trace the Java or Jython call that terminates it. Again, with Jetty as an application server, running the same Jython code it runs flawlessly. I am in the process of verifying whether I can switch to Jetty, but if I'll find a solution to this tomcat issue, I'll keep you posted.

The usual culprits are:
- a stack overflow error is being triggered and automatically disables the tracing (unfortunately, this may not be uncommon and it does break the debugger)
- some application is using sys.settrace itself (which also breaks the debugger).

Hi, I manage to connect to the debugger from a remote Jython script (running in localhost). i can step over the python calls, but at some point the script resumes and continues without me hitting resume. Same happened in both PyCharm and Eclipse. I have also tried using Jython directly or through JSR-223 scripting but got the same results.
Thanks
