Summary: ReactiveThrottler: possible starvation
Key: JAMES-4019
URL: https://issues.apache.org/jira/browse/JAMES-4019
Project: James Server
Issue Type: Bug
Affects Versions: 3.8.0, 3.8.1
Reporter: Benoit Tellier
Fix For: 3.9.0
In production I encountered logs saying there was too much concurrent IMAP
request.
>From a starting point in time, my IMAP server stopped accepting request and
>could not continue progress. Complete dead lock.
By careful unit testing of ReactiveThrottler I was able to diagnose it was not
handling "cancel" correctly and not propagating to items in the queue which
would cause the deadlock.
Note: one can avoid this fully by disabling IMAP throttling.
