Getting this error a lot in Sidekiq (Retries and Dead lists):
Jobs::HandledExceptionWrapper: Wrapped ActiveRecord::RangeError: PG::NumericValueOutOfRange: ERROR: integer out of range
The jobs I’ve noticed this identical error for are:
Jobs::PostAlert
Jobs::ProcessPost
Jobs::NotifyCategoryChange
This was discussed a bit in the past here: Feedback on the new Review Queue - #250 by markersocial
Can you please run:
cd /var/discourse/
./launcher enter app
su postgres
psql
\x
\connect discourse
SELECT id FROM notifications ORDER BY 1 DESC LIMIT 1;
\q
exit
Thanks @Falco, I just ran it now. Here is the result:
-[ RECORD 1 ]--
id | 2147483496
Okay, so it’s the famous integer max problem. We need to move to bigint to fix this. I will take a look into this.
For now your workaround is to run:
cd /var/discourse/
./launcher enter app
su postgres
psql
\x
\connect discourse
ALTER TABLE notifications ALTER COLUMN id SET DATA TYPE bigint
\q
exit
This is the default for new installs but old installs have the wrong data type.
Running the workaround may be hard cause it will block the table, you many need to shed your web load first.
Thanks @Falco & @sam - appreciate it 
Regarding the workaround, this should be relatively safe to do? Not worried about down time, just breaking something.
It’s using the standard app.yml single container. For shedding the web load, do you think using read-only mode and running ./launcher stop app, ./launcher start app prior to doing the workaround probably suffice?
It will not break anything, worst case is that it will just be “stuck” for a very long time.
Thanks Sam, I did the workaround. Though, did not get any feedback upon inputting:
ALTER TABLE notifications ALTER COLUMN id SET DATA TYPE bigint
Not sure if it’s still processing perhaps. Currently getting the same error (in the /sidekiq dead list, for last retry ‘just now’ jobs) for:
Jobs::PostAlert
Jobs::ProcessPost
Jobs::NotifyCategoryChange
Looks like you need to run in with post_id column as well
Thanks!
Just to be sure, does this look correct?
ALTER TABLE notifications ALTER COLUMN post_id SET DATA TYPE bigint
Yes that should be safe, once we add an official migration it will allow for it
Perfect, thanks
I ran that (no confirmation/feedback received, like the previous one). Forum didn’t slow down, so not sure if it worked. Getting the same errors currently.
Maybe it would be best if I wait for the official migration.
Yeah looks like this is in the post_alerts table, we need to sweep through many tables
Curious where you are on this issue now? Did the errors stop?
Originally we were thinking of making some official migration here, but the risk far outweighs the benefit. We find it exceedingly rare to come across DBs with more than 2,147,483,647 posts. 2.1 billion is a real big number.
The downside of increasing the sized everywhere are that storage requirements go up.
Where we are now is that we are considering adding a rake task that “makes space” if you are in an outlier case where you have tables in Discourse that containe 2 billion rows (or had 2 billion rows of churn)
Thanks for the follow up @sam
I just upgraded to 2.8.0.beta6 and still getting the integer out of range errors.
I think that it’s just the notifications that has got to a massive number, which is a bit more realistic to reach the limit compared to number of posts. A lot of large topics with many replies, likes etc. from different users can result in quite a lot of notifications.
A rake task sounds fantastic
これは古いスレッドだと承知していますが –
devforum.roblox.com でも同様の問題が発生しました。v2.8.9 を実行していますが、まもなく 3.0.1 にアップデートする予定です。
ユーザーが投稿に「いいね」または「いいね解除」しようとした際に 403/500 エラーが表示されるようになったため、何かがおかしいことに気づきました。
このスレッドを見つけ、通知テーブルを確認しました。
=> SELECT id FROM notifications ORDER BY 1 DESC LIMIT 1;
id
------------
2147483647
(1 row)
@sam 上記の回避策は依然として最善の提案でしょうか、それとも 2021 年 9 月以降、rake タスクについてさらに検討されましたか？
詳細情報 –
notifications.id 列を変更した後、Jobs::PostAlert ジョブで別の問題が発生しています。
Job exception: 2147498514 は、limit 4 bytes の ActiveModel::Type::Integer の範囲外です
他に不足しているテーブル/列があるのでしょうか？ それとも、まだ整数データ型を期待している Ruby のどこかにあるのでしょうか？

はい、これがここでの唯一の回避策です。コアを変更することについては心配ですが、これを修正しないと、巨大なフォーラムでこの問題が発生し続けると思います。
欠点はストレージの増加です。
post_actions サービス（または通知プロセス内のどこか）で、ALTER を実行した後に整数を期待している箇所があるかご存知ですか？
/post_actions へのいいね/いいね解除の呼び出しで 5xx エラーが発生しており、レスポンスは以下のようになっています。
{"errors":["The requested URL or resource could not be found."],"error_type":"not_found"}
さらに、通知に関するジョブの失敗（Jobs::BookmarkReminderNotifications、Jobs::GrantAnniversaryBadges、Jobs::PostAlert）もいくつか発生しています。
前のメッセージで PostAlert のバックトレースを追加しました。notification.rb の consolidate_or_create で整数制限に関する問題が発生しているようです（notification.rb）。
機能が復旧できれば、ストレージの増加はそれほど懸念事項ではありません 
コンテナを再起動してみてはどうでしょうか。メモリにキャッシュされたものが原因かもしれません。
