Re: [Iscsitarget-devel] Strange iSCSI / IET Behavior [Errors when Writing]

Hi,

I modified it and set it to 16384 as requested.  I
attached the tcpdump of the login process.  I also
still get the too lond messages and the dd takes a
realy long time.  Running top shows istd1 using 99.9%
of CPU usage.  A sample follows of the lond data
messages follows:
