As I'm sure others will mention, this is a quite old cyrus now with many 
known bugs.

You chould definitely consider upgrading to Simon Matters RPMs

We used to see this every now and then as well, but it's stopped since we 
fixed this bug:

I'm not sure if Bron has commited this back to cyrus CVS for the next 
release yet, but if not, it should definitely get included.

I think it's either a coincidence (eg the bug is not iSCSI related), or if 
it is iSCSI related, it's not directly related, and probably just caused by 
timing race changes created by a change in the storage layer.
