I have been running with MyEclipse 8.6 just fine until recent updated about 2 weeks ago. Not sure what got updated. But I keep getting “Cannot connect to VM” everyone once in a while. Not sure what is causing this. See attached screenshot.

After 3-4 attempts, it seems to give in and I am able to run our app in DEbug mode just fine. I added the line -clean on eclipse.ini hoping it was not related to any cache. No luck. The message pops-up randomly. Many developers have witnessed this in older releases of MyEclipse

Any ideas?

Thanks!

AT,

Thank you for the installation details and .log file. I am afraid we could not replicate the same here. Could you try the following for me –

1. Open Window > preferences > Myeclipse > servers > Integrated Sandbox > Tomcat 6. From the right hand pane click on [Restore MyEclipse Tomcat Server Installation], [Apply] and [OK] and restart the IDE.
2. If it is still an issue, could you try out the solution posted by the user – “grr” solution here – https://www.genuitec.com/forums/topic/socket-closed-cannot-connect-to-vm-when-debugging/

Let me know how this works for you.

Best.

I tried the items you listed in your response below and neither helped. The Tomcat randomly does this so I’m not sure if this has anything to do with Windows 7 x64-bit updates from Microsoft.

I installed MyEclipse 9.0 hoping to alleviate the issue. But MyEclipse 9.0 has its own set of issues. The same project that works fine in 8.6.1, shows innumerable JS errors in 9.0 despite disabling JS validation and including a rule to exclude *.js files.

I had to eventually uninstall 9.0 after trying different things. So I am back to square one – patiently trying to start Tomcat in 8.6.1 and hoping it starts Tomcat. I still have the intermittent “Cannot connect to VM”.

Until MyEclipse fixes the JS errors in 9.0 I really cannot upgrade.

AT,

You mentioned that you recently updated MyEclipse 8.6 in some way. Have you remembered what you updated? As something changed, that is likely to be the problem, since I can’t reproduce the error here.

Is there any pattern to when the error occurs? Are you doing other work outside MyEclipse that might interfere? Does it only happen after several successful debug sessions? If so, maybe the last server launch wasn’t cleaned up properly. Or there might be insufficient memory – could you try increasing the memory allocated to MyEclipse, in the myeclipse.ini file? You could also try launching the server in debug mode to check it starts up OK, then debug your application by launching the integrated web browser and invoking your application from that.

If you still have intermittent problems, you could try reinstalling 8.6, to get a clean install. What extra plugins have you installed?

It’s possible to have both the 8.6 and 9.0 releases installed at the same time. It would be useful if you could reinstall 9.0, if you get time, and open a separate topic here, regarding your JS validation issues. In that way, we could help you resolve those problems so that you could make 9.0 your main workbench.

Apologies for the continued problems.
