Hi,
I got all excited about IMAP NOTIFY support and tried enabling
mailbox_list_index on my server. Unfortunately, I rather quickly ran
into trouble of the segfault variety. This prevented me from doing
basic things like seeing the contents of some of my folders. Disabling
mailbox_list_index got me back up and running, but... darnit, that's
annoying. The only message I got in my log file was this:
imap(user at domain): Fatal: master: service(imap): child 6899 killed with signal 11 (core dumped)
If I can help track this down, please let me know. Here's the
backtrace:
