Now with PVE 3.2, I had read a complaint in the PVE forum of Mr. 
jens.kuespert "Since updating our testing-environment we experience strange 
backup errors. We backup three VMs, which are using a LVM-storage.  The 
backup is done with snapshot mode. using Two backups are proceeding without 
error, the last VM is crashing during the backup. The only diffrence I can 
see is, that the crashing VM has four virtual harddisks. How can I get my 
fingers on the cause of that behaviour? Is there any log-file I could read? 
" , please see

Any idea for fix?
