MailScanner's running as root:smmsp here. And it delivers mail fine,
 marking spam via SA and finding viruses with ClamAV and f-prot, it's 
 just the one or two processes which do nothing but eat CPU.

  PID USER     PRI  NI  SIZE  RSS SHARE STAT %CPU %MEM   TIME COMMAND
27667 root      20   0 30892 3156  3116 R    94.9  2.2 113:15 MailScanner

This process, for example, did not a single syscall in the last 3 hours, 
 according to strace -v -F -F. Other MailScanner processes come and go 
 and Just Work. It has the following filedescriptors open:

lr-x------    1 root     root           64 Nov 20 18:06 0 -> /dev/null
l-wx------    1 root     root           64 Nov 20 18:06 1 -> /dev/null
l-wx------    1 root     root           64 Nov 20 18:06 2 -> /dev/null
lrwx------    1 root     root           64 Nov 20 18:06 3 -> socket:[211931924]
lr-x------    1 root     root           64 Nov 20 18:06 4 -> /usr/local/MailScanner/lib/MailScanner/CustomConfig.pm
lr-x------    1 root     root           64 Nov 20 18:06 5 -> /usr/local/MailScanner/lib/MailScanner/ConfigDefs.pl
lrwx------    1 root     root           64 Nov 20 18:06 6 -> /var/spool/.spamassassin/bayes_toks
lrwx------    1 root     root           64 Nov 20 18:06 7 -> /var/spool/.spamassassin/bayes_seen
lrwx------    1 root     root           64 Nov 20 18:06 8 -> /var/spool/.spamassassin/bayes_toks.new

And it can't be a permission problem, IMHO, because the other 
 MailScanner processes behave. Note that all this started when I 
 upgraded from 4.23 to 4.25.6.

/var/spool:
drwxrws--T    3 root     mail         8192 Nov 20 18:03 .spamassassin
drwxr-s---    2 root     smmsp        8192 Nov 20 18:04 mqueue
drwxr-s---    2 root     root        49152 Nov 20 18:04 mqueue.in

/var/spool/mailscanner:
drwxr-xr-x    9 root     root         4096 Nov 20 17:31 incoming
drwxr-sr-x   18 root     root         4096 Nov 20 00:13 quarantine

cheers,
