Cannot connect to the physical desktop

[wagometer]

Hi, I can log into my NX Workstation server (Centos 6.5) from windows, however, I cannot get a physical desktop. When I look at the nxserver log I get the following repeated:

2015-06-09 17:18:49 232.115 15488 NXSERVER WARNING! Cannot write to FD#10.

The file continues to fill. I also notice that nxserver child processes continue to be spawned, but then crash.

I have attached the logfile.

Please help.

Thanks

Can you send the log files to forum[at]nomachine[dot]com?

Hi Britgirl,

I have sent the log.

I also noticed a lot of core.##### files in my home directory. So, I ran gdb on them and found they are coming from the nxclient.bin. I attached the output from gdb for one of the core files to the email as well.

Thanks

Hello wagometer,
We will need debug NoMachine server logs to investigate further. Please follow the instructions here:
https://www.nomachine.com/AR07K00677
Send them to forum[at]nomachine[dot]com

After enable debug logs on problematic machine please execute:
/etc/NX/nxserver --restart
and after that try to reproduce the issue.

Additionally please provide output of command:
ps -Af | grep X

We need more information about crashed process. Please find the script attached and execute:

./cdebug.sh /usr/NX/bin/nxclient.bin <corefile>

The script will generate a file named <core file>-details.log.

Please send it to us also.

Hi haven,

I have uploaded most files to the forum. I was not able to upload the /usr/NX/var/log directory because it’s ~120MB zipped. The log file itself is 800MB. It’s that big because I had to wait for the crash to occur, which took ~1 day.

How can I get that large file to you?

Thanks

@wagometer, send them to forum[at]nomachine[dot]com. Please put the title of your topic in the subject. Thanks.

Britgirl,

I misspoke. Sorry. I did email them to forum[at]nomachine[dot]com. I will resend.

 

[Britgirl]

Got them.

[wagometer]

Any update?

[Britgirl]

Hi, we sent you an email asking you to upload the 120 MB of server logs. I will send it again.

[wagometer]

I removed all the files because the partition my system is on was filling up. The logfile grew to several GB and there were numerous core dump files. I’ll work on reproducing this and send the updated bundle to the forum email.

Thanks
