Dear all,

I am sorry to have another post.
I have been following a problem which has been growing fast on our system.

At the beginning I thought it was related to load on PG server, then I thou=
ght it was load on the switch/network, now I don't know.

We seem to get loads of Exception errors and when I look at the Postgres Lo=
g there are loads of "duplicate key value violates unique constraint"

I have researched on the Internet and some posts say: Reindex, some say bug=
in JIRA.
Some say: Your primary key index isn't in sync.

Have you guys suffered from this problem before, or have seen it anywhere?

From 30th of April to today I got 1400 errors.
What do you guys think might cause this behavior?
I also think it is causing the system to slow down a bit, do you think that=
might be possible?

Very much appreciate any help, insight, opinion or anything you could think=
..

Thank you very much


Best regards

Renato
