<span id="spnSign20135231621"></span><div>&nbsp;dear all,</div>
<div>&nbsp;&nbsp;&nbsp; Recently my MailScanner do not run very 
well.MailScanner&nbsp;SpamAssassin&nbsp;Timeout randomly,and when SpamAssassin&nbsp;Timeout,the 
MailScanner process will occupancy CPU 100%,and after a few minutes ,the 
MailScanner process will also&nbsp;occupancy all memery,then the system load is too 
high ,and the system can't work.</div>
<div>&nbsp;&nbsp;&nbsp; I google it,do as the people said,set spam.assassinprefs.conf :</div>
<div style="FONT-STYLE: italic">use_bayes&nbsp;1 </div>
<div style="FONT-STYLE: italic">bayes_auto_expire&nbsp;0 </div>
<div>&nbsp;&nbsp;&nbsp; But it can't fix the problem.then i run</div>
<div>#MailScanner&nbsp;--debug&nbsp;--debug-sa </div>
<div>&nbsp;&nbsp;&nbsp; I found the point.Every time when the&nbsp;MailScanner process occupancy CPU 
100%,the log is stop at:</div>

<div>...............................</div>
<div>&nbsp;</div>
<div>&nbsp;&nbsp;&nbsp; I don't know why and how to fix it.And i found when i run</div>
<div>&nbsp;</div>
<div>#MailScanner&nbsp;--debug&nbsp;--debug-sa </div>
<div>&nbsp;</div>
<div>&nbsp;&nbsp; The MailScanner process will release resources after&nbsp;30 seconds,when i 
run(i set <span style="FONT-STYLE: italic">Max&nbsp;Children&nbsp;=&nbsp;5</span>)</div>
<div>#service MailScanner start</div>
<div>&nbsp;</div>
<div>&nbsp;&nbsp; The MailScanner process which occupancy CPU 100% will not release 
resources .....And after a few minutes,maybe more MailScanner process will 
occupancy resources&nbsp;,and after all the system is hung.I even set&nbsp;&nbsp;<span style="FONT-STYLE: italic">SpamAssassin&nbsp;Timeout&nbsp;=&nbsp;10</span> ,but can't fix 
either.</div>
<div>&nbsp;</div>
<div>&nbsp;&nbsp; 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>
