[Koha] problem importing marc records

[Huck]

from staging to managing the staged records to completing the import...

my server running nothing but Koha 3.0 (only 2GB partition) it's a test 
server so that's all that was available atm..

appeared to be running out of space...
in /var/log/mysql
I noticed:

-rw-rw---- 1 mysql adm   1611014 2008-04-07 12:01 mysql-bin.000006
-rw-rw---- 1 mysql adm 105149302 2008-04-07 12:01 mysql-bin.000005
-rw-rw---- 1 mysql adm       672 2008-04-07 12:01 mysql-bin.index
-rw-rw---- 1 mysql adm 104955729 2008-04-07 11:57 mysql-bin.000004
-rw-rw---- 1 mysql adm 104889615 2008-04-07 11:52 mysql-bin.000003
-rw-rw---- 1 mysql adm 104987514 2008-04-07 11:47 mysql-bin.000002
-rw-rw---- 1 mysql adm 104906029 2008-04-07 11:42 mysql-bin.000001

honestly having no clue what they do/did were used for...
I assumed(yes we know what that means :) that these were sort of 
temp/log files of what mysql-bin was doing ...so in essence recording 
every single transaction or something...
and the one with the highest number kept incrementing...and would get to 
it's size limit it seems every 5 min...

so right now I'm monitoring and deleting each of the ones below the 
highest numbered(in filename)...attempting to stave-off the 'out of disk 
space' which was causing this process to 'hang' on Friday.

Any thoughts?
