Problems with 2.2.10 on HPUX 11i

[Connie Starr Fensky]

I've just upgraded to imap 2.2.10 (with sasl 2.1.10) on my 11i mail server. I did this on a test box, but could not simulate our load (several thousand connections, ~80000 messages delivered a day), and had no troubles. But, of course, putting on the mail server and starting up, performance is abhorrent. I'm running 100% cpu utilization AND memory utilization all of the time, which make the whole system sluggish and the users grumpy. All my fault, and I need to fix it yesterday. 

I have a pretty basic system--same as can be to my old 2.0.16 one that ran like a dream.
Does anyone have any ideas for me--here is configure script:
# csf 12/13/04 This is the command I used for configure
CC=/opt/ansic/bin/cc CFLAGS='-g +DAportable +z' LDFLAGS='-L/usr/local5/db-3.3.11/lib 
-L/usr/local5/lib -L/usr/local/lib' LIBS=-lpthread ./configure -with-auth=unix 
--with-cyrus-prefix=/usr/local5 --prefix=/usr/local5 --with-sasl=/usr/local5/cyrus-sasl-2.1.20/ 
--with-dbdir=/usr/local5/db-3.3.11 --with-bdb-libdir=/usr/local5/db-3.3.11/lib 
--with-bdb-incdir=/usr/local5/db-3.3.11/include --with-lock=fcntl --with-mboxlist-db=flat 
--with-openssl=/usr/local5 --disable-sieve --disable-gssapi

and imapd.conf
allowusermoves:         1

tls_cert_file:          /var/imap/server.pem
tls_key_file:           /var/imap/server.pem

and cyrus.conf--had to lmtp -a just to get any messages to deliver, and just made changes to maxchild, prefork to try to improve perf.
By the way, it takes almost two hours to finish ctl_cyrusdb -r, and it seems like it is hanging, because if I kill that process, master starts for a split second.

# standard standalone server implementation

START {
  # do not delete this entry!
  recover       cmd="ctl_cyrusdb -r"

  # this is only necessary if using idled for IMAP IDLE
#  idled                cmd="idled"
}

# UNIX sockets start with a slash and are put into /var/imap/socket

  # add or remove based on preferences
  imap          cmd="imapd" listen="imap" prefork=9

#  lmtp         cmd="lmtpd" listen="lmtp" prefork=0
  lmtpunix      cmd="lmtpd -a" listen="/var/imap/socket/lmtp" prefork=5 maxchild
=9

  # this is only necessary if using notifications
#  notify       cmd="notifyd" listen="/var/imap/socket/notify" proto="udp" prefork=1
}

EVENTS {
  # this is required
  checkpoint    cmd="ctl_cyrusdb -c" period=30

  # this is only necessary if using duplicate delivery suppression,
  # Sieve or NNTP
#  delprune     cmd="cyr_expire -E 3" at=0400

  # this is only necessary if caching TLS sessions
#  tlsprune     cmd="tls_prune" at=0400
}

Thanks for any help! As usual, I'm under the gun...
