[SM-USERS] question about files in /tmp

[<ho...@mo...>]

Hi,

We have SM 1.4.0 on RedHAt FC1 Linex.  It is running well.  I have a
question about files in folder /tmp.   That folder shows a lot of files
that seem to stay "forever", e.g.

-r--------  1 apache apache  41587 Jun  8 11:24 phpa_2304_51244
-r--------  1 apache apache  10366 Sep 12  2003 phpa_2308_160995
-r--------  1 apache apache  93788 Sep 13  2003 phpa_2308_161002
-r--------  1 apache apache   2811 Jun  2 14:54 phpa_2308_161006
-r--------  1 apache apache   6084 Jul 12  2003 phpa_2308_176783
-r--------  1 apache apache  26691 Jul 19  2003 phpa_2308_176798
-r--------  1 apache apache  12927 Oct 12  2003 phpa_2308_176805
-r--------  1 apache apache  79214 Oct 12  2003 phpa_2308_176806
-r--------  1 apache apache  48047 Dec 31  2002 phpa_2308_18823
-r--------  1 apache apache   2137 Jun  6  2003 phpa_2308_176828
-r--------  1 apache apache   1928 Apr 27  2003 phpa_2308_177020
-r--------  1 apache apache  62699 Mar 11  2003 phpa_2308_18682
-r--------  1 apache apache  10607 Mar  2  2003 phpa_2308_18688
.....

Some of them have timestamp of 2002!  Actually, I just installed this new 
fc1 system and SM last month.  Are these files created and used by SM?
Should they be deleted automatically after some time of period?  If not,
should I remove them manually?  If I should, then what is a good time to
remove them? once a day, once a week, or?  I don't want to affect any
user if them are used by some user's SM.

Thanks a lot!
