I installed PINE 3.88 on our MUSS System in Dec. 93. MUSS is running  
SunOS 5.2 Generic on a SUN Sparc. Our System Analyst reports the problem 
below. Has anyone had a similar problem? I remember seeing dialogue on 
the read/write lock/unlock but don't recall the details. Thank you in 
advance. Your help is really appreciated.

Subject: Pine on Solaris

Carolynn:-

	There seems to be a problem using PINE on MUSS.  I am not sure if 
the problem is with the students or a coding problem or a combination.  I 
have a large number of defunct processes.  This in itself is unusual.  I 
have been having MUSS re-booted to clear these up once a week.  
Unfortunately, the occurance of these defunct processes is increasing 
more rapidly than before.  I have traced these defunct processes back to 
running PINE.
	My request is this:  Would you ask the question of the PINE 
support group (or the interest group) if anyone else is experiencing this 
problem.  It looks like the process has the mail box open and another 
Pine process can't get control of the inbox to open for read-write.

	Thanks.

I reported a problem to the pine-info mailing list last week, but got no
response.  Each day I am having to delete about 10 processes left around
by uses of Pine.  Help!  Anybody got any ideas of what's going on.  The
message is repeated below.  Reading your description above, it would
appear that my problem is different to yours.

Subject: one rsh left around after Pine finishes

We run three variants of Pine 3.89:

   sun    for computers running SunOS 4.1.2 and SunOS 4.1.3
   sol    for computers running SunOS 5.2 and SunOS 5.3
   hpp    for computers running HP-UX 9.01

All uses of Pine on these machines use IMAP to access the user's inbox.
The IMAP daemons run on a SunOS 4.1.3 computer called venus.  We are using
the version supplied with Pine 3.89, namely IMAP2bis Version 7.5(72). 

When Pine is run, it sets up two rsh processes to venus:

   rsh venus exec /etc/rimapd

When Pine 3.89 (or 3.88) is run on a SunOS 5.2 machine, sometimes one of
the two rsh processes still remains after the user has left Pine.  This
happens quite often during the day.  But I haven't worked out why it
happens on some occasions and not on others. 

Is this a known problem?  Has anyone else seen this?

I've seen what might be a related problem with the 2.3 rshd.  If you run
truss on the stuck process and see it spinning in a 'wait() Err#10
ECHILD' loop then it's the same problem.  Haven't seen anything about rshd
in the Solaris patch database; maybe one of this week's socket/tcp/kernel
patches will fix it.  Then again, maybe not.

Barry and Carolynn,

The latest version of the IMAP distribution contains improved process
management code that will hopefully solve or improve this problem.  If you
would like to try it, get mail/imap.tar.Z from ftp.cac.washington.edu.  
This distribution may also be substituted for the imap subtree of Pine 
3.89 if you really want to be on the cutting edge.  NOTE, this code is 
still considered experimental and has not been extensively tested on some 
platforms!

Thanks for the report!
