<div> Recently my MailScanner do not run very
well.MailScanner SpamAssassin Timeout randomly,and when SpamAssassin Timeout,the
MailScanner process will occupancy CPU 100%,and after a few minutes ,the
MailScanner process will also occupancy all memery,then the system load is too
high ,and the system can't work.</div>
<div> I google it,do as the people said,set spam.assassinprefs.conf :</div>
<div style="FONT-STYLE: italic">use_bayes 1 </div>
<div style="FONT-STYLE: italic">bayes_auto_expire 0 </div>
<div> But it can't fix the problem.then i run</div>
<div>#MailScanner --debug --debug-sa </div>
<div> I found the point.Every time when the MailScanner process occupancy CPU
100%,the log is stop at:</div>

<div> Stop at here ,and the MailScanner process occupancy CPU 100%, then
after 30 seconds(because i set <span style="FONT-STYLE: italic">SpamAssassin Timeout = 30</span> ), the log will go
on:</div>
<div> </div>

<div>...............................</div>
<div> </div>
<div> I don't know why and how to fix it.And i found when i run</div>
<div> </div>
<div>#MailScanner --debug --debug-sa </div>
<div> </div>
<div> The MailScanner process will release resources after 30 seconds,when i
run(i set <span style="FONT-STYLE: italic">Max Children = 5</span>)</div>
<div>#service MailScanner start</div>
<div> </div>
<div> The MailScanner process which occupancy CPU 100% will not release
resources .....And after a few minutes,maybe more MailScanner process will
occupancy resources ,and after all the system is hung.I even set <span style="FONT-STYLE: italic">SpamAssassin Timeout = 10</span> ,but can't fix
either.</div>
<div> </div>
<div> So,are there any friends know how to fix this problem? Thx!</div><br><br>---------------------------------------<br><font size="2"><a href="http://mail.21cn.com/m/21cn/index.html " target="_blank">21CN手机邮Android客户端，邮件随身享！ </a><br></font></dongwind@21cn.com><br><br>---------------------------------------<br><font size=2><a href="http://mail.21cn.com/m/21cn/index.html " target="_blank">21CN手机邮Android客户端，邮件随身享！ </a><br></font>
