Hello, I got an old mailsystem to upgrade running cyrus 2.5.10 on a debian stretch. Upgrading this system to debian buster, running cyrus 3.0.8 as a first step, following the upgrade advisories I ran into the following issue: ctl_conversationsdb ran for about a day I guess and finally ended with an segmentation fault. Investigating the issue i figured out, that it is caused by one specific user mailbox about 43 Gb in size. Other similar Mailboxes produce a conversations db of under 70 Mb, but for this particular one, the db grows and grows and grows until it's 4 Gb in size and ctl_conversationsdb crashes. Any ideas what could cause this issue and how to debug this? My guess would be some mail that causes ctl_conversationsdb to get somehow stuck in a loop, if that's possible.
