System lockup during Poudriere build

[James Koenig]

Dear FreeBSD-PKG email list,                                                   
                                                                               
    Have any of you had a successful poudriere build of the entire ports       
tree using ZFS as a primary RAID manager, including swap?  If so, what         
kind of hardware or configurations did you use, in terms of RAM, number of 
CPUS, etc?  When we've tried to run a poudriere bulk build on our entire   
ports tree, we've experienced the build server totally locking up over      
file locks. These lockups happen consistently during the build (poudriere  
bulk -a) process, whenever ZFS's swap is enabled, and no longer occur when 
ZFS's swap is disabled.                                                    
                                                                               
a crash filesystem's core.txt from the described lockup is attached as     
zfs_lockup.core.txt.gz
 
Regards,
