Hi Everyone
One of the 5 application servers in our production environment has
started to have performance problems, starting at about 8:59 EDT
yesterday morning according to our monitoring tools. The problem was
actually reported via an php web site that is running on the same server
that makes web service calls to the local instance of Sakai and also
accesses the same database server. According to the catalina.out and
apache logs, there was no unusual activity at that time. Our network
monitors don't show any unusual traffic levels either.
I have done a reboot of the system and restarted Sakai (without letting
any users near it). During the start process, there appears to be a
very long pause with the last line in catalina.out being
2011-04-04 10:17:33,310 INFO main
org.sakaiproject.site.impl.DbSiteService - init(): site table:
SAKAI_SITE external locks: true
Normal start up times are around 75000 ms, this mornings was 332045 ms.
The SAKAI_LOCKS table is empty when this is pause occurs.
Does anyone have any suggestions.
Thanks
Tom
