Hi,
My bacula-sd is deadlocking during copy jobs.
Version 5.0.1
compile option: --with-readline=/usr/include/readline --disable-conio
--with-mysql --enable-smartalloc
Linux version: i686-pc-linux-gnu debian 5.0.4
Daily i copy every job made that night from 2 disk pools to a migrate pool
using copy jobs (pool uncopied).
The migrate pool contains a autochanger with to drives. Config of the bacula-sd
autochanger see below.
Both pools are loadbalancing there jobs over the 2 drives (using the maximum
concurrent jobs =1 feature in the bacula-sd) as expected.
After a while the load on both the dir and sd are dropping to 0.
When I try to do status stor in the console I see the following (stopping at
Used Volume status: and waiting forever):
*status stor
The defined Storage resources are:
1: Migrate
2: diskbackup
3: diskbackup2
Select Storage resource (1-3): 1
Connecting to Storage daemon Migrate at bacula-sd.solcon.nl:9103

I dont understand the part
thread apply all bt
Please help me out
Thanks and regards,
