Hello again,
Here's my info: Xwiki Enterprise 1.7.2 with multiple spaces. I just
migrated this wiki from another organization that was using version
1.4.2 (in case that makes a difference in my question). Environment:
centos 5.2/apache 2.2/tomcat 6/mysql 5.1
Yesterday, we encountered errors on various pages (though not all)
like the following:
Error number 4001 in 4: Error while parsing velocity page /templates/
xwikivars.vm Wrapped Exception: Failed to evaluate content with id [/
templates/xwikivars.vm] Error
number 4001 in 4: Error while parsing velocity page /templates/
htmlheader.vm Wrapped Exception: Failed to evaluate content with id [/
templates/htmlheader.vm]
All the errors had some mention in the stack trace of trying to do an
operation on the database after it's been disconnected. So we changed
the JDBC url specified in the xwiki hibernate config file (/usr/local/
tomcat/webapps/xwiki/WEB-INF/hibernate.cfg.xml) to add the
"autoReconnect=true" attribute and restarted Tomcat. That did away
with the errors and we thought it was fixed.
Well it happened again today. Looks like xwiki is getting into some
state in which things start failing, after being up for some period of
time or getting some number of user requests or something. But we are
having severe personnel issues - so don't have anyone who knows much
about tomcat to help us debug. If anyone else has come across this it
would be a big help.
One possible thing I can think of - since it mentioned velocity
templates - when i migrated the wiki, i installed the default XAR -
then I imported the mysql dump - could this have overwritten the new
templates? If so, is re-importing the default XAR advisable on a live
wiki?
Thanks for any help,
Cristina
The following is a paste of the first error encountered (very long):
Error number 4001 in 4: Error while parsing velocity page /templates/
menuview.vm Wrapped Exception: Failed to evaluate content with id [/
templates/menuview.vm]
A problem occured while trying to service your request. Please contact
the support if this happens again.
