Recently i've opened case in the dell support. They found some issues with stor2rrd statistics collection:
"Found lots of messages which indicate that the database might be
experiencing a congestion which is causing high pressure on the database - ddsh: INFO: SQLITE: rc=5, database is locked"
"Found something like a script or so running excessively on the DD, and its running lots of commands
and this user is “stor2rrd”.
We are suspecting this might be a cause for the high pressure
experienced by DD registries so please check this user/script and try to
for now so that we can check the system behavior afterwards.
Its not advisable to keep running this script excessively as this might cause performance issues for the DD."
I don't want to disable DataDomain statistics collection - it is very usefull. But there is plenty errror messages in the DataDomain log such as "database is locked" or "Too many logins for stor2rrd".
Is it possible to increase an interval between probes or there can be a different solution?
