hi

since i've upgraded bacula from 2.2.x to 2.4.4 (both backport.org 
versions) the full backup (about 3TB) gets a "Connection reset by peer". 
dir, sd and fd are on the same network, connected to the same switch - so 
no NAT inbetween. with 2.2.x also 4TB backups were no problem. 

after searching the web, i've found many references to "heartbeat 
interval". turned on on dir, sd and fd. 

i've started the job 3 times, 2 times without "Heartbeat interval": they 
we're failing after 8h and 11h. the last one with "Heartbeat interval = 
1m" failed after 11h. 

joblog shows this:

both filer and backup hosts are debian etch with 2.6.26 (backports.org) 
kernel. 

any hints how to track down the problem? anyone had the same problem?
