V1.0 CPU Usage

PostPosted: Mon Aug 06, 2012 1:20 pm
by pete
After upgrading to V1.0 I am noticing very high CPU usage as soon as I start serviio.

I am running on Ubunut 12.04 with java version "1.7.0_04", Java(TM) SE Runtime Environment (build 1.7.0_04-b20). I have had the server running for several hours and I am pretty confident it has completed index on some of those occasions.

I have turned debugging on and I see when serviio is checking files which I guess is normal. These scanning logs are indicating that the files are already in the library.

But I am seeing high CPU loads even when it appears that it is not updating files to the library.

I have attached visualvm to see what is going on and I see several threads running at 100% (see thread dump below). Memory appears stable and GC activity is very low

So is any one else seeing this behaviour?

Thread dump.

If you enable detailed log is there anything happening at this time?

With detailed logging there is nothing happening at that time.

Looking at the thread dump I figured that it might be something to do with the plugin scripts that I have. So stopped the server removed them all and no CPU spike. I repeated the process adding in each script one at a time checking to see if the problem reoccurred. I have managed to add them all back in and the CPU is ok (strange). I haven't checked if they work again, but as I understand it there shouldn't be a reason why they shouldn't.

This is a bit odd as it was systematicly maxing the CPU on each boot of the machine.

I will try a reboot next to try and get the problem to occurs again.

the plugins might cause this if they are not properly coded. Also might happen if the plugin takes too long to process data, but Serviio will kill it after 30 secs - obviously if there are a lot of feeds or feed items that migh still block for a long time.

Re: V1.0 CPU Usage

This seems like it is the issue. I have about 18 feeds configured mostly the groovy scripts where taken from here: http://forum.serviio.org/viewtopic.php?f=20&t=3820 apart from one. I had this configured http://forum.serviio.org/viewtopic.php?f=20&t=6802&p=48742&hilit=rage#p48742. When I started looking into this problem I removed these feeds as a guess, given that was probably the script least used by other people. Even after removing the feeds (from the console) I still had the issue, which is why I looked further.

So I have added them back in and found that the site (mentioned in the second link) is down. I have no idea for how long or if the server was misbehaving at some stage. At the moment I am not seeing the CPU problem (with these feeds added back in). I can't recall seeing the Exception on the failed attempt to connect to the URL (it could have been lost in the noise).

Unless there is something odd with OnlineLibraryManager cache and a site that becomes unresponsive (I can only guess as to weather the cache is persisted between executions of the server). It would appear that the problem lies with a misbehaving script.
