Sorry, I meant networking gremlins in general, not the descriptor
problem. I run Slackware, and the default kernel is still 2.4.x. Once in
a while I set up a server with a 2.6.x kernel, but it never makes it out
of the punishment closet. YMMV.

The only thing I saw when troubleshooting my own problem was it always
seemed to affect users that had just received a message. I couldn't
verify that this was anything other than a coincidence (IOW, it was
nonreproducable).

I still have idled running, it's just causing problems when the client
(mainly Thunderbird) attempts to use it. Other clients worked fine with
IDLE enabled.

I can only show you how I compile mine on Slackware:
./configure --prefix=/usr \
--with-bdb-libdir=/usr/lib \
--with-bdb-incdir=/usr/include/db4 \
--enable-idled
make depend
make all CFLAGS=-O
BTW, SquirrelMail works extremely well on my own server after switching
to Cyrus IMAP. I don't think you're experiencing a client issue. You may
need to perform a packet capture and analyse the conversation between
server and client. This can be frustrating work when the error is
transient, though.
