Hi.
I recently upgraded Cyrus to 3.2.2 from 3.0.13.
Now threading "UID THREAD REFS US-ASCII ALL" on one specific folder with
>50K mails,
makes imapd process use 100 CPU% without any progress. truss[1] or dtrace
shows no output. The process seems totally stuck.
I installed in a FreeBSD 12.1 jail. Any hints beside the online docs of
how to use gdb to
see what is going one. I could not make imapd run under gdb even with
the -D option
and debug_command setting or reading
https://www.cyrusimap.org/imap/developer/developer-testing.html?highlight=debug
It is fast enough on other folders also with ~50k mails < 3 secs.
Any hints, highly appreciated :-)
