Loads of stale zero byte tmp files?

[Remco Barendse]

Hi list

I have an issue with MailScanner-4.84.5-2 / SpamAss on CentOS 6.2. The 
setup seems to be working ok but i have an issue on 2 boxes that temp 
files do not get deleted.  In /tmp stuff like this is piling up quickly:
-rw-------. 1 root    root         94 May 20 22:55 K2M0qbNwv6
-rw-------. 1 root    root          0 May 21 05:08 tmp.1t3DQ6ZFaU
-rw-------. 1 root    root          0 May 21 06:14 tmp.9ZRV7VB41Y
-rw-------. 1 root    root          0 May 21 04:17 tmp.DmqX7lvDJS
-rw-------. 1 root    root          0 May 21 04:17 tmp.HwtJIyJImI
-rw-------. 1 root    root          0 May 21 06:14 tmp.MdrrIsMqGa
-rw-------. 1 root    root          0 May 21 05:08 tmp.ToMnIIFMf1

and in /var/spool/MailScanner/incoming/SpamAssassin-Temp :
-rw-------. 1 root root 0 May 21 06:31 MailScanner.UfuR0E
-rw-------. 1 root root 0 May 21 05:58 MailScanner.vpJ3tf
-rw-------. 1 root root 0 May 21 03:34 MailScanner.zmZPln
-rw-------. 1 root root 0 May 21 03:34 MailScanner.zTSxkI
-rw-------. 1 root root 0 May 21 05:42 tmp.1t1IUXAFLV
-rw-------. 1 root root 0 May 21 05:42 tmp.296NAlpKdS
-rw-------. 1 root root 0 May 21 03:35 tmp.3cDHk7cwub
-rw-------. 1 root root 0 May 21 03:20 tmp.3eimiawowx


Any clues why the temp files are not getting deleted?

Thx!
