When a container or driver is started (ping is successful) Selenoid does a new session request just in the same way as standard Selenium client.ĭepending on what is returned as response on the previous step session is marked as created or failed. This is done by sending HEAD requests to the port. Before proceeding to next step Selenoid waits for required port to be open. All requests during startup are marked as pending. When there is a free slot for request Selenoid decides whether a Docker container or standalone driver process should be created. Queued requests just block and continue to wait. When requests reach the limit - subsequent requests are placed in queue. Selenoid -limit flag specifies how many sessions can be created simultaneously. Running Selenoid in custom Docker networkĪ new session request arrives to Selenoid. Running Selenoid in default Docker network Syncing Browser Images from Existing File Specifying Capabilities via Protocol Extensions Links to Application Containers: applicationContainers Video Recording: enableVideo, videoName, videoScreenSize, videoFrameRate, videoCodec Custom Screen Resolution: screenResolution Right-click the process you want to stop and select End task. To display the PID column, right-click the header row and select PID from the list. Open the Task Manager application ( taskman.exe), from either the Processes or Services tab sort by the PID column. If you get permissions errors, you may need to use the sudo keyword, for example: sudo kill -9 44475 For Windows Use -9 option to make sure the process dies immediately To find the process id (PID) associated with the port ⇒ lsof -i tcp:3000 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME node 44475 chen5 31u IPv4 0x8b1721168764e4bf 0t0 TCP *:strexec-s (LISTEN) You know the process is occupying a particular port on your machine or server. In order to do that, you need to find the process id (PID) of the process. When this EADDRINUSE issue has already happened, in order to resolve it, you need to kill the process manually. On crash, do process.on('uncaughtException'.The proper fix for the application would be It is only called when the event loop ends, and since server.close() sort of ends the event loop (it still has to wait for currently running stacks here and there) it makes no sense to put that inside the exit event. ) isn't called when the process crashes or is killed.
