Fog client 0.10.6 error "Object Reference not set to an instance of an object"

[Tom Elliott]

Try updating again please.

I’m trying to figure out how to correct for an issue of query packet sizes. I added a timeout that I think you’re seeing being hit. Most of the time, the connections are handled in a persistent state. 10 seconds forces the DB to di of 10 seconds of inactivity.

I’m on 7601 and have the same issue, only just updated from 7561, was fine before. I am pushing a new image.

@Tom-Elliott I am now on 7605 and it appears to be doing the same thing:

EDIT: now the Apache logs say line 7 FYI

@Tom-Elliott new Apache error in log:

Fri May 13 08:00:25.107051 2016] [:error] [pid 17793] [client 10.1.106.146:49243] PHP Fatal error:  Function name must be a string in /var/www/html/fog/lib/client/printerclient.class.php on line 7

just rolled back to 7561, all working again.

@Tom-Elliott I’m not helping by posting snippets of the apache log. Want the full one? I’m noticing errors on different lines now.

@fry_p Printer Client message should be fixed.

With any luck the db lost issue should be corrected for again. Please try and thank you for the info so far.

@Tom-Elliott On 7609, the client is back to normal. In fact, my snapin fired off too! Thank you my friend!

The message “Object not set to instance of Object” means that you are trying to use an object which has not been initialized. That is, you either set it to null, or you never set it to anything at all. The runtime throwing a NullReferenceException always means the same thing: you are trying to use a reference. The reference is not initialized (or it was initialized, but is no longer initialized).
