@EzrealerQAQ need browser container logs.

@vania-pooh browser container logs:

@EzrealerQAQ probably your cluster is just overloaded.

[EzrealerQAQ]

@vania-pooh deploy stand alone by docker,ram 200G+ left，cpu 1.7 used ，storage 5T left, i'll try to deploy in a new server

[EzrealerQAQ]

but it seems the reson of error is about ffmpeg or x11grap as [x11grab @ 0x7ff23a8633c0] Cannot open display browser:99, error 1. browser:99: I/O error

[vania-pooh]

@EzrealerQAQ video recorder is unable to access X server because it does not start for some reason. X server is anyway started in browser container. These messages Waiting X server... should take 1-2 seconds maximum. Probably you are also running Selenoid in some restricted environment preventing X server from start.

[EzrealerQAQ]

@vania-pooh thank you very much,i can't find what to prevent X server from start,maybe a new clear server would work...

[vania-pooh]

@EzrealerQAQ we are testing everything under Ubuntu. in case of using CentOS probably turning off SELinux can help.

[EzrealerQAQ]

@vania-pooh i use centos7, [root@ezrealer selenoid]# getenforce Disabled and anthor new clear server also don't work...

[EzrealerQAQ]

i add try to my program

        while True:
            try:
                driver = webdriver.Remote(command_executor=command_executor,
                                          desired_capabilities=capabilities, options=self.options)

                break
            except Exception as e:
                print(e)
                time.sleep(1)

every try could success,so strange....

[vania-pooh]

@EzrealerQAQ try under Ubuntu is possible.
