81,vbulletin 3.6.4 / 3.6.5 rare fatal errors viewing threads w xcache 1.0.3,vissa,moo,"Vbulletin 3.6.4 (security patched)
RHEL4
php 4.4.5
xcache 1.0.3 (compiled from source -- you are missing this version in your ticket dropdowns)

Overall xcache is running excellent.  However, I have had sporadic reports of users getting the following error when clicking a thread after using ""new posts.""  I have also seen reports of this at vbulletin.com.

'''Fatal error: Direct instantiation of vB_Postbit class prohibited. Use the vB_Postbit_Factory class. in /includes/class_postbit.php on line 239'''

Here is a link of other reports of this error at vbulletin.com

I also noticed when upgrading from vb 3.5.3 to 3.6.5 on another forum that there were some problems during the upgrade that never happened before xcache. May be unrelated.  I had to disable xcache for moodle on one site (I'll make another ticket for that).
