Communication error on wallboard
« on: January 11, 2011, 07:25:31 »
Hi,

Since a few days our wallboard gives an error around 5 PM with the following error code:

Communication error: RPC server did not send response before timeout

What does it mean and how can we solve this?

You should be looking at the QM logs and see if there is an error there as well, or it is just the processing of data that takes too long.

Since 2 months it happens and always on the same time around 5, we didn't change anything. Around 5 pm there are almost no callers.
In which log could there be information?

When the screen refreshes, it's working again so it's a quit strange error.

Try looking under /usr/local/queuemetrics/tomcat/logs if you see anything generated.

There are some localhost_log files which are around 2GB each

Likely on catalina.out as well.
Try and delete all files, restart QM and wait until the error happens.

Probably this is the code of the time when the error came... do you know if there is anything wrong here?

Class: it.loway.app.queuemetrics.autenticazione.preparaParametriReport
Class: it.loway.app.queuemetrics.validazione.logon

Nothing wrong, a Java Stack trace would be quite long and visible.
The system seems pretty snappy - it reloads all data for the realtime report in 40 to 60 msec.

But is there something we can do to not get the Communication error anymore?

I really should see the error - you sure there is none?

I could send/show you a daily log? Because it happens every day between 17.00 PM and 17.10 PM.
It's a catalina.out log of 3.4 MB

I did check and there is nothing like an error on the log.
I suspect that for some reason (maybe a cron job) the server is very loaded at that moment so the client times out.....
