1.3.0-RC-7 high load

[ablohowiak]

Ubuntu 14.0.4.4
After updating to RC-7. I’m seeing a huge increase of network traffic to the DB server.

The portal has also become slow to respond because the load.

The apache error log is full of entries like:

[:error] [pid 15993] [client :51945] PHP Fatal error: Uncaught exception ‘Exception’ with message ‘Window size must be greater than 1’ in /var/www/html/fog/lib/fog/fogurlrequests.class.php:62\nStack trace:\n#0 /var/www/html/fog/lib/fog/fogurlrequests.class.php(46): FOGURLRequests->rolling_curl(NULL)\n#1 /var/www/html/fog/lib/fog/fogurlrequests.class.php(157): FOGURLRequests->execute()\n#2 /var/www/html/fog/lib/pages/dashboardpage.class.php(109): FOGURLRequests->process(Array)\n#3 /var/www/html/fog/lib/fog/fogpagemanager.class.php(72): DashboardPage->bandwidth()\n#4 /var/www/html/fog/management/index.php(19): FOGPageManager->render()\n#5 {main}\n thrown in /var/www/html/fog/lib/fog/fogurlrequests.class.php on line 62, referer: http://fog/fog/management/index.php?node=home

How many storage nodes do you have? How many are on and working?

@Tom-Elliott
32 up and running. A few others that are disabled.

I’m trying to reach you via chat, hopefully we can do a remote session, and I can see what’s happening.

If you get time, please try the patch as proposed in the following link. It should prevent runaway loops.

For the high network load, it’s a replication bug in RC-6 and 7. I can confirm the RC-8 fixes the replication issue.

@Tom-Elliott
I added the one line, and we’ll see how things behave today.
Thanks.

@ablohowiak Don’t know if 9 hours is enough, but did it help at all? Now that RC-8 is released, you may try simply updating first.

@Tom-Elliott

The code change definitely made a difference and the load mostly stayed in the single digits yesterday.

[Tom Elliott]

@ablohowiak Do you think it’s safe to solve?

[ablohowiak]

@Tom-Elliott Yes. Thank you.
