All bugs fixed in 5.0.1 have been marked as such. 
 
Please be warned that any 5.0.1 patches available in Bugzilla must not work
for you. They where contributed, and most of the time this usually only
means that they may have worked for the contributor.
 



Best Regards,
Alex.

        Anyone know.  This is kind of critical.  If they aren't patched
already I'd like to know if I have to go through each critical item and
patch it myself.

Could you send the .class pathc or the .jar patch ( and the .java ), please?


It would be very useful for me. 

Thank you very much

FYI I commited the fix to the CVS (even though I changed the hashCode
implementation slightly).

          That bug is not fixed in 5.0.1.   I am actually patching it
myself.  I am going to take Christian's suggestion and email the bug author
to make sure the patch is  applied correctly.

Thanks to everyone for the responses. 

My experience with OpenCMS without stress testing has been great, but under 
stress of 600 users hitting the site at least 10 to 20 times each a day, 
even running the refresh cron job overnight hasn't been enough, as it 
crashes during the day with the OutOfMemory Error, or starts giving strange 
error messages with MySQL (Can't find COLUMN FILE_CONTENT being one on pages

it has been happily serving before) before crashing. It would be possible to

run the site statically exported to Apache instead which is a workaround I'm

trying to implement, thus reducing the number of people hitting the CMS 
application. Any pointers on static export gratefully received. (I've been 
going through the opencms.properties file, but have a problem getting pages 
to point to the correct place for images and css files pathed to module 
directories when statically exporting) 

Darin: Yes, I am running lucene, do you have optimisation tips for this or 
experiences you could share. TIA 

Joachim: Could you give a quick system spec, i.e. version of OpenCMS, RAM, 
whether you are running a "refresh" script overnight, user load etc. 

>From the point that Christian and Cory raised, has that bug been fixed in 
5.0.1? 

Daniel: Thanks, a quick question though, are you sending -Xmx/ -Xms 
parameters to the JVM as well as the cron "refresh" script? 

Kind Regards 

Kemi
