Hi,

since one week ago, my daily backups are taking more than 2 days to
complete! I dont know why yet, but just one directory in a client
machine (host2:/var/vpopmail) is taking a lot of time, as seen in the
output of the amstatus below. Here is the amanda proccess right now
running in the client machine:

amanda   32319  0.0  0.1  1552  436  ??  S    Mon07AM   0:12.50
/usr/local/amanda/libexec/sendbackup
amanda   32320  0.0  0.1  1552  352  ??  S    Mon07AM   4:47.62
/usr/local/amanda/libexec/sendbackup
amanda   32322  0.0  0.0   628    0  ??  IW   -         0:00.00 sh -c
/usr/local/bin/tar -tf - 2>/dev/null | sed -e 's/^\\.//'
amanda   32323  0.0  0.1  1068  372  ??  S    Mon07AM   2:47.97
/usr/local/bin/tar -tf -
amanda   32324  0.0  0.1   972  368  ??  S    Mon07AM   0:10.05 sed -e
s/^\\.//

Im not using compression neither in the server or the client.
host2:/var/vpopmail contains 2.4 GB of data, with 168577 files.

The strange is that it begins to happen with no reason.... 
My guess is that gnu tar is eating all the time...
