[jira] Created: (MRM-1291) Archiva has periodic load-peaks
Archiva has periodic load-peaks
--------------------------------
Key: MRM-1291
URL: http://jira.codehaus.org/browse/MRM-1291
Project: Archiva
Issue Type: Bug
Components: system
Affects Versions: 1.2.2
Environment: RHEL4, Oracle RDBMS
Reporter: Marc Lustig
Attachments: cpu-day.png
Archiva causes periodically an increased system-load. (see Munin-stats attached)
During these peaks calling the homepage takes around 6 secs, whereas normally it is around 1 sec.
I could not identify corresponding messages in the logs.
Could somebody else observe this?

I want to provide you a third chart (cpu-week2.png).
The filled area shows the "blown-up" load on the left half.
The second half shows the normal load.
All seems to be caused by the periodic scan processes.

-----------------------------------
did you have any large change in artifacts / rebuild the index in that period?
I'd like to encourage you to try 1.2.3-SNAPSHOT or the release - the hourly peaks will certainly be reduced. If it seems managable, we can close this out.

Marc Lustig commented on MRM-1291:
----------------------------------
This pretty much sounds like a reasonable explanation - unfortunately it may not be the (only) reason.
I forgot to mention that this "periodic peaks" load-pattern occurs only from time to time.
I. e. when the pattern happens, the peaks occur periodically. But after restarting Archiva, the pattern does not occur anymore for a couple of days or weeks.
I can be sure about this because we have notifiers installed that warn when a certain HTTP-request on Archiva exceeds a certain threshold value.
We have not seen alarms between 3rd of november and 30th of november.
On the 30th out of a sudden the periodic load raised tremendously.
I doubt the RDBMS being slower could have an impact on the load.

Marc Lustig updated MRM-1291:

Please have a look at the second stat-chart by Munin.
Unfortunately we miss the data between week 46 and 48.
But when you look at the filled area in week 45, you can see very the apparent load-difference between normal scanning peaks and "overblown" scanning-peaks.
By the way, we do not have any other software running on that server.
