Hi
Just some good news, my old issue
https://cyrus.topicbox.com/groups/info/T9aaa6a2c6f46f713-M8e510b8b9d2403f299d68854/uid-thread-refs-us-ascii-all-slow-stalls-forever-on-one-folder
I solved with an upgrade from 3.2.5 to 3.4.2
I have not confirmed but I guess the following did it:
Fixed CVE-2021-33582: Certain user inputs are used as hash table keys
during processing. A poorly chosen string hashing algorithm meant that
the user could control which bucket their data was stored in, allowing a
malicious user to direct many inputs to a single bucket. Each subsequent
insertion to the same bucket requires a strcmp of every other entry in
it. At tens of thousands of entries, each new insertion could keep the
CPU busy in a strcmp loop for minutes.
