Hello, There is something unclear for me.

HAProxy 2.6.10 was released on 2023/03/10. It added 78 new commits after version 2.6.9. A bit more than half of the commits are HTTP3/QUIC fixes. However, as indicated in the 2.8-dev5 announce, a concurrency bug introduced in 2.5 was fixed in this version, that may cause freezes and crashes when some HTTP/1 backend connections are closed by the server exactly at the same time they're going to be reused by another thread. Another different bug also affecting idle connections since 2.2 was fixed, possibly causing an occasional crash. One possible work-around if you've faced such issues recently is to disable inter-thread connection reuse with this directive in the global section: tune.idle-pool.shared off But beware that this may increase the total number of connections kept established with your backend servers depending the reuse frequency and the number of threads.
Is this a workaround for the previous versions or one need to apply this setting also to the current version ?
Thank you for your clarification. -- Best regards, Artur
