Hy all,   I have a big problem with spamassassin, my system is a Intel(R) Pentium(R) 4 CPU 3.06GHz with 626,63 MB of mem and swap 2,0 GB with Red Hat Enterprise Linux ES release 2.1 running - Qmail with 5 concurrencyincoming process setting, - spamassassin-2.63-1, - clamav-0.70, - qmail-scanner-1.22. - perl-Mail-SpamAssassin-2.63-1, - perl-suidperl-5.6.1-37.1.99ent - perl-5.6.1-37.1.99ent During normal operation the number of Spamd process is equal to 1 or two, see below...   -------------------------   6:28pm  up 12 days,  8:48,  1 user,  load average: 0,35, 0,14, 0,10 73 processes: 71 sleeping, 2 running, 0 zombie, 0 stopped CPU states:  4,0% user,  0,4% system,  0,0% nice, 95,6% idle Mem:   641664K av,  547336K used,   94328K free,      56K shrd,  331816K buff Swap: 2096440K av,   12984K used, 2083456K free                   45824K cached     PID USER     PRI  NI  SIZE  RSS SHARE STAT %CPU %MEM   TIME COMMAND 21290 spamd     15   0 89128  86M  2108 S     0,0 13,8   0:04 spamd 21267 qscand    21   0 13356  13M   784 S     0,0  2,0   0:00 clamd ---------------------   But sometimes without any notice number of Spamd process grow without any control to 10 or more ,RAM and Swap Mamory was filled and system stucked..   The situation come back to normal after stopping any process of spamd and the restart main spamd process.   It is seems as there are almost two main spamd process see below...   - /var/log/maillog .....
