Subject: Problem of using Pine 3.05 in NFS environment

Dear Sir,

	I have recently came across a problem of using Pine 3.05 in our NFS
environment.

	If a user's home directory is at local hard disk (not NFS mounted),
 we never came across the problem. However, if a user's home directory is NFS
 mounted, user can only send mail and cannot open other folders, the terminal
 will be hung up. Folder INBOX is marked "READONLY". Then, a dead pine process
 will stay on the workstation and cannot be killed by user or super user.

	Our environment is :

	 Application server : HP9000/755 running HP-UX 9.01 

	 NFS server : HP9000/800 model G50 running 9.0

	I have also used the newly created Pine 3.87, and the problem still 
happens.

	If you have any suggestions, please don't hesitate to contact me.

	Thanks & regards.

Frank,

It looks like you are being bitten by the notorious NFS file locking
problem.  Our recommended solution is to install an IMAP server (imapd) on
the system(s) that has the local storage.  This way the IMAP server can
manage all of the locks locally without having to worry about rpc.lockd
bugs.  We are working on ways to bypass the NFS locking problems, but do
not have a completely satisfactory solution yet. 

Thanks for the report!
