Debugger doesn't stop on a breakpoint. Debugger shows “Command timed out”. What to do?

This is definitely a bug that we'd like to investigate. So please do the following:

  • go to Help | Debug Log Settings
  • add #com.jetbrains.cidr.execution.debugger there
  • reproduce the problem
  • collect debug logs, logs can be found in Help | Show Log in <File Manager>
  • send logs to us via submitting a request here and attaching log files.

Update: If you have a timeout problem, you can also try and increase the timeout value.


Recently we've published CLion 2016.2 EAP build, which includes major changes in GDB and LLDB drivers and addresses such problems as:

  1. Command timeouts.
  2. Stepping problems.
  3. Debugger performance issues.

Please, find more details in our blog post.


This still happens with attach to process GDBs.


It will be a good idea to write exactly this mini-tutorial as it is in CLion.

For example there is no "Help|Show Log" option, but "Show Log in File Manager"


Tau, what is not clear from the instruction, except for the path to find logs in the menu (which differs for every platform, so I guess Show Log was enough to get it, but could extend)?


For example "Help | Configure Debug Log Settings" does not exist, looked for it for 30seconds, I searched it in another mensu, because I was expecting to start with "C" from "Configure". But in CLion it's "Debug Log Settings" :)


Thanks Tau. Seems the name in the menu changed after the article has been published. Updated here.
