Frequently getting booted off

[jjgalvez]

I am connecting to NoMachine 6.6.8 running on Ubuntu 18.04 from NoMachine 6.6.8 on Arch and I am getting kicked off the server frequently. When I look at the server logs I see several WARNING! Error is: 32, ‘Broken pipe’ errors. Also the nxd log file is showing several 23548 23780 14:08:34 540.726 DaemonServerApplication/DaemonApplication: WARNING! Child process 23781 died with signal 9, SIGKILL. errors.

Not sure what to look at to fix this.

Hello jjgalvez,

please enable debug, restart nxserver, reproduce the problem and send logs to forum[at]nomachine[dot]com using as mail’s subject, the title of that forum’s thread ‘Frequently getting booted off’.

The whole procedure of how to collect logs is described in the article:
https://www.nomachine.com/DT10O00163 (“How to gather debug logs for support requests”)

regards

I send the log files today. Sorry it took me several days to get back to this, things got busy at work and I was unable to log into this machine to reproduce the issues until now.

Thank you for reviewing the log files, hopefully something will reveal itself.

Hello

The logs from the server are suggesting the problem may be either with the player or with the internet connection itself, as our agent reports no data from the player for an extended time (over 1 minute) without the connection actually breaking.

Can you explain what are you experiencing on client side when you are “kicked off”? Is it straightforward termination of connection without error, and going back to “recent connections” screen? Or there is “spinning wheel” screen between?

Please also provide us with the client application logs as explained in the point 2 of the article:

https://www.nomachine.com/DT10O00163 (“How to gather debug logs for support requests”)

Please note that if there isn’t any error in the player application, you will have to disable log cleaning and reproduce the problem again.

Please send us the logs as previously.

Also as there may be indication of unstable connection, please make sure there is no problem in the system logs on both machines (with the logs more suggesting the problem is on the client side).Common problems may be caused e.g. by router IP lease time configuration or ISP interfering with some ports usage.

Thank you, on the client side the screen becomes unresponsive for a couple of seconds and then I get the “spinning wheel” and eventually I get a time out error.

I will reproduce the error again and generate regenerate both the server and client logs and send them to you again. Of note the error happens regardless of of the client host. I was on the machine this morning from a mac on a different network and got the same error.

I reproduced the error again this morning and I am sending the server and client logs.

Thank you again for your help with this issue

Hello.

There is one more possibility to check.
When connecting to the server, are you using any kind of services through player like disk or printer sharing or file transfer?

If you are, please check if one of those is not causing the connection problem by disabling them, or if there is any correlation between using them and disconnection.

If this fails, I’m afraid the only thing that is left to consider is a connection problem. Here are two points:

– If you have dynamic IP address, please check if the renewal is not happening at the time of disconnection.

– The connection address is within the Oracle dynamic DNS service address pool. This is another potential weak spot for the connection.

Thank you Mth, at least I feel better that it is not some NoMachine issue that causing the problem. The problem does not seem to be connected with a service. Ordinarily I don’t connect to any unless I need to and then it’s usually only the drive for a short period of time. I suspect it is a connection problem with my mother’s ISP. I’ll have to trouble shoot that the next time I am there.

Thank you again for all your help
