Alfresco getting stoped while accesing pdf files from document libary

We have an Alfresco Community edition , version 3.4 installed on a Windows 2008 server. We are using this alfresco as our DMS. Yesterday we found some unusual issue in alfresco.
After login, we go for a particular site, select Document Libary, change folder , select PDF at that time alfresco got stopped. We tried to access the docs and xls files in the same site, but no issues, also we checked some other PDFs in other sites no issues.

Solution :
1. In Alfresco server we installed Open Office.
2. Stop Alfresco
3. C:\Alfresco\tomcat\webapps\alfresco\WEB-INF\lib i have updated fontbox-1.5.0.jar and pdfbox-1.5.0.jar from http://archive.apache.org/dist/pdfbox/ and http://archive.apache.org/dist/pdfbox/1.5.0/
(Old versions in the system are pdfbox-1.2.1.jar and pdfbox-1.2.1.jar)
4. Start Alfresco

Checked the document library, pdf and everything is working fine.
I spend 6 hours for fixing this issue.

Adding multiple ssl virtual hosting

For this we need to add another ip to the machine.

/etc/network/interfaces

auto eth0:1
iface eth0:1 inet static
address 192.168.1.122
netmask 255.255.255.0

/etc/init.d/networking restart
Check ipconfig -a

/etc/apache2/ports.conf
NameVirtualHost *:80
Listen 80

<IfModule mod_ssl.c>
    # If you add NameVirtualHost *:443 here, you will also have to change
    # the VirtualHost statement in /etc/apache2/sites-available/default-ssl
    # to <VirtualHost *:443>
    # Server Name Indication for SSL named virtual hosts is currently not
    # supported by MSIE on Windows XP.

    Listen 192.168.1.121:443
    Listen 192.168.1.122:443
    NameVirtualHost 192.168.1.121:443
    NameVirtualHost 192.168.1.122:443
</IfModule>

<IfModule mod_gnutls.c>
    Listen 443

how to disable or turn off the ssl_redirect option in bugzilla

Bugzilla setup I made a rookie mistake of enabling SSL without any SSL mods loaded on Apache. Now i can't access Bugzilla site using either https or http
how to disable or turn off the ssl_redirect option

Login to the server
cd /var/www/bugzilla (Your bugzilla document root)
Edit your data/params file, change ssl_redirect to 0.

This helps.
