Odd error (b3248)

[BigOkie]

I'll preface this by saying I searched for this and there are a few posts here, but I'm using b3248 currently (waiting for some of the issues I'm seeing from people in b3257 to update it).

This morning I woke up to trying to access the dashboard on Cumulux but getting a very vanilla looking template with no data (looked like no CSS was being processed).

Did a service restart and that took quite a while, long enough that I killed it. Checked the service and sure enough it had stopped. So I manually started it again. Checked the log files and saw a BUNCH of these errors that had started last night:

It appears to repeat for every realtime interval (for me that's five seconds). I'm not doing any ftp uploading, I host my own internally and map NFS drives so I can just do local copies. Works for me. Was hoping a stop start would alleviate this but it didn't.

What did alleviate it was a complete reboot of the RPI I have CMX installed on. I know what to do in this case now, but was wondering what might be trying to access that file as I don't have a lot going on with file transfers aside from doing the local copies. I'm assuming the double forward slashes for directory separators wouldn't do that, as that's never been an issue before

Thanks.

You could find if a process on the pi has the file open with...

Code: Select all

ls -l /proc/*/cwd | grep 'web/realtimegauges txt$'

You need to run that as root though.

Potentially an issue with the NFS mapped drive if it took a reboot to fix it.

My thought too. I've had very little issues with that. If I notice it next time I'll see what it's doing with Mark's command. Thanks for the responses guys.
