misc lock/write problems

I get two types of errors when procmail runs on my mail server:
procmail: Error while writing to "_-80Glaguna"
procmail: Lock failure on "pete.lock"

With this .promailrc file:
#!/bin/sh
# default procmail definitions and recipes go here.  This runs as root!
# pmk  10/9/96
#
#  chmod 544 for normal operation
#  REMEMBER to chmod prior to editing!
#
#

PATH=$HOME/bin:/usr/bin:/usr/sbin:/usr/local/bin:
MAILDIR=/var/spool/mail
DEFAULT=$MAILDIR/pete
LOGFILE=$MAILDIR/pete.log
LOCKFILE=$MAILDIR/pete.lock

#set this for debugging
VERBOSE=on

# If a mail is to ME, not from a list
#  then page me with the subject

| Mail -s "$MATCH" 9094482100(_dot_)xxxxx(_at_)pagenet(_dot_)net </dev/null

#end of .procmailrc

and these file permissions:

for /var/spool/mail
drwxr-xr-x   2 mail     mail         1024 Aug 11 15:17 mail/

and within the mail dir.
-rw-------   1 pete     mail            0 Aug 11 15:18 pete
-rw-r-----   1 pete     mail         1476 Aug 11 15:18 pete.log

I get this in my procmail logs:
