cumulus 1.8.8 monthly log file issue

[btenveen]

Hi,

About every two or three days I have to restart Cumulus 1.8.8 because the monthly log file is not updated anymore.
Because of this I downgraded back to 1.8.7 this version doesn’t have that problem.
Is this a known issue or am I the only one with this problem.

Could you zip up your diags folder (while running 1.8.8, after the problem has occurred) and attach it, please.

[btenveen]

I re-activated 1.8.8
The next time it happens i send the zipped diag folder.

Last night the logfile was not updated anymore.
I stopped Cumulus.
Because the process kept running I had to kill it with task manager.
Attached you find the diags.

It looks like it stopped updating at about 04:36, but it's not obvious why. You have lots of these errors:

2010-01-18 04:56:55 : 4:56:55 FTP Error: FTP component not connected

These are several times a minute, so presumably this is realtime ftp. It looks like you have some sort of connection problem to the ftp server. I don't know if this is related to the problem or not. But towards the end you are getting many more of these per minute, so maybe it is related.

A short while after it stops updating, you get this:

2010-01-18 04:51:37 : Error processing web\indexT.htm Error: I/O error 32

This is a "sharing violation", in other words something else is preventing Cumulus accessing the file. It may be that something similar has happened to the log file - but it's odd that there is no error message for that.

Other than these observations, it's hard to say what the problem is. But it does look as though the realtime ftp is having serious problems - this is probably why you had to kill the task.

I've just noticed something: When you started Cumulus the time before last, it had a lot of data to download from the logger, and it looks as though you closed it down again straight away, and then started it again. It hadn't actually finished running when you started it again - the thread which writes to the diags file runs in the background and if it has a lot to do, it carries on running after Cumulus appears to have closed. So it's never a good idea to let it download a lot of data, close it straight away, and then start it again. I should probably make this clear in the documentation.

The ftp errors started immediately when you started it up again, possibly because it was still running. I know it appeared to run for quite some time before it stopped logging, but perhaps the problems stem from this.

Probably the FTP errors are caused bij heavy local network traffic.
I'm running several backup jobs during the night.
Maybe the file sharing violation is also because of this (the backup job locks the file).
It is strange, with version 1.8.7 I also see thoose ftp errors, but the monthly log file update keeps working.

Possibly. It's odd that there's no message for the logs, though. When it stops updating the log file, is it still updating the display?

It is strange, with version 1.8.7 I also see thoose ftp errors, but the monthly log file update keeps working.

I've seen others with the same errors (thought not quite so many) and it doesn't seem to stop their log being updated either.

Yes, display and web files are beeing updated.
By the way my settings for updating are every 1 minute and realtime every 30 secs.
