278882 - junk filter causes Mozilla to use 100% CPU

Status: RESOLVED WORKSFORME

(SeaMonkey :: MailNews: Message Display, defect)

Description

[doeni]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8a6) Gecko/20050111
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8a6) Gecko/20050111

Since 20050116 when starting up Mozilla mail, the CPU usage goes up to 100% when
the junk filter marks new mails as Junk.
Mozilla mail worked fine until 20050111. So problem must have started to appear
between those 2 builds.

I tried deleting the training.dat, and initially the problem did not reproduce.
However after marking a few messages as junk, the problem reproduced.

Mails are stored on POP3 server.

Reproducible: Always

Steps to Reproduce:
1. Startup mozilla mail (junk filter must be enabled)
2. Let mozilla mark new mails as Junk, or manually mark some mails as junk

Actual Results:  
Notice Mozilla using 100% CPU


Expected Results:  
normal CPU usage

Build arguments :
--enable-application=suite --enable-default-toolkit=gtk2 --enable-calendar
--enable-xft --disable-postscript --disable-xprint --enable-crypto
--disable-installer --disable-debug --enable-optimize=-O3

The same arguments were used to build the working mozilla mail application.

Bug looks similar to bug 262743, but deleting training.dat does not solve the
issue here.
