I'm seeing some odd (wrong) behavior with Plan 9's upas/fs and was wondering of others have seen it, before I start digging further. I use upas/fs to talk to a local mailbox and two IMAP servers. The local store and one of the IMAP servers work reliably correctly. On the other IMAP server, upas/fs will *sometimes* get into a state where when I remove a message, it'll re-insert itself into the tree with a higher message number. For example, with the IMAP server dalet:
:; cd /mail/fs/dalet :; ls 1 2 ctl :; rm 1 2 ; ls 3 4 ctl Messages 3&4 are the same as 1&2; nothing new's actually come in. Other IMAP clients I've used behave properly with this server. I've not yet identified the pattern which causes it, but it's not random. Anyone else seen this or similar?
