Access to locality pages

Posted by Larry Maltby

Over the last couple days I have been having trouble pulling up locality pages when I am logged in. When I select a locality page nothing happens and I cannot move to any other pages. I must close Mindat and reopen. If I am not logged everything works fine. I hope someone can help.

I just ran through a bunch of different pages at 1:34 pm CDT and had no issues.
I am logged in (obviously) as well, so perhaps something on your end is buggered up??

The server has been overloaded recently. I suspect that it has to do with the database engine getting bogged down doing some queries.

One of the pitfalls of operating such a successful website, I suppose... ;-)

I observed this error message:

Fatal error: Call to a member function fetch_object() on a non-object in /home/mindat/www/loc.php on line 107

after a few minutes of waiting

Everything is working again. I am a very happy guy!

Thanks for the help, Larry,
Larry Maltby September 13, 2017 04:15PM
Ouch, the problem is back.

Larry Maltby September 13, 2017 06:50PM
Everything is now working again. This confirms Dave's point that It only happens during times of peak usage.
I have also found that I can work around it by uploading photos manually by pasting in the location in the space provided and doing the location check. Just a little more work.
Rolf Luetcke September 14, 2017 02:16PM
I had those same problems yesterday and assumed it was the peak usage issue and seems that is the case.
With such a huge site as mindat now is, we are surprised it works as well as it does.
I had those "fatal error" issues a while back also but not recently.
Yesterday it was as Larry had said and I just waited and later it worked again, out again, worked again.
One has to work around those things and carry on.
All in all, things do work fairly well.
Rolf Luetcke September 19, 2017 01:50PM
Had those same problem yesterday and today also.
Things seem to hang up and go nowhere and I finally found a way around this.
When I am not logged in things seem to go fine but logged in it won't go to locality pages, just hangs up.
I found that if I go to my page to add a photo and use my personal add photo it goes smoothly but if I try to go to the location it won't go there.
Fortunately I found a different way that seems to work normally.
Hope that this can be fixed since it is boring to sit and twiddle my thumbs waiting for a page to open and then nothing happens.
If anyone else is having this same problem, to add photos, try using your personal page to add photos.
Funny things do happen but when I thought it was due to heavy use I tried it again very early this morning and same thing so it is probably not that.

I am still having the same problem; two hours ago I could not get into the locality pages while logged in. I just tried again and got right in.

Uwe Kolitsch September 19, 2017 04:08PM
There are still daily periods when the server is inaccessible.
Ralph Bottrill September 19, 2017 09:44PM
Having the same problem again today, mostly when logged in.
Jerry Cone September 20, 2017 11:06AM
Rolf, thanks for the work-around. It seems strange to me that if the server is bogged down anything should work, but your method does.
Larry Maltby September 20, 2017 01:32PM
I just noticed that the start of this problem correlates very closely with the start of the live posting of the Denver Show Report. My first post above was on Sept 12 and the live posting of the show report started about Sept 10. I wonder if the WIFI at some Denver hotel was hacked while up loading the report.
David Von Bargen September 20, 2017 02:22PM
No, it's just some queries that are running for the new non-hierarchial localities that are taking a lot of time and locking the locality table and causing other programs that want to access it have to wait. It started when a couple of very large localities like this were added on the 8th .
Uwe Kolitsch September 20, 2017 02:48PM
Is it possible to restrict such queries to not occupy more than, let's say, 5% of the bandwith?
Jolyon & Katya Ralph September 20, 2017 03:00PM
I don't know of any way to do this.
David Von Bargen September 21, 2017 01:49AM
Its not a bandwidth problem, when the tables are locked by a query, no other query can use them, so they wait until the table is unlocked. This builds up a queue that will eventually use up connections to the database.
Uwe Kolitsch September 21, 2017 03:19PM
I see - thanks David.
