Using Pine 4.21-23 as supplied with Red Hat Linux 7.0 the program hangs
when switching from a folder such as sent-mail back to the INBOX. The INBOX
is an IMAP folder on a Red Hat Linux 5.1 running imap 4.1.final-1. The bug
is very reproducible, and independent of the local folder that is closed.
Can't reproduce from Red Hat Linux 7 to Red Hat Linux 7, so this looks like some
weirdish interaction between new pine and old imap-server... Can you at least
try the one in Red Hat Linux 5.2? (5.1 isn't supported anymore)
The problem does not have to do with the IMAP server, but with the NFS locking
problems between RedHat 7 and older versions of RedHat.
Oops, forgot. The local folders are on an NFS-mounted homedirectory. That is why
the NFS locking bug gets triggered in the first place. See bug #18097.
So the Red Hat 5.1 system is running IMAP, and it is mounting an NFS
mail spool from elsewhere? What is the NFS server running on?
All I can recommend is to upgrade to a newer version of Red Hat Linux
on the affected systems. 5.1 isn't supported as Trond mentioned. This
bug doesn't appear to be imap related, but as you say NFS related so I'm
