Articles not created sometimes

Hello together,

we are using RT 4.2.8 on Debian 8 with Postgresql 9.4 and tried to create some articles this morning
but we have received the following error: “Internal Error: Couldn’t execute the query 'INSER INTO Articles (Created,Creator,Summary,LastUpdateBy,Class,LastUpdated,Name) VALUES(?,?,?,?,?,?)'ERROR: duplicate
key value violates unique constraint “articles_pkey” DETAIL: Key (id)=(24) already exists”

After some tries the article will be created anyway.

I can confirm that the ID is already in use but we haven’t seen the error before.

Is there anything to solve the problem? (Yes, we already update the system soon :wink:

Thanks in advance!
