Hi Mark,

I am the developer of the ioreplay app (ioapps suite). I came across this post, 
could you please provide more details on the problem with replaying of 
"incomplete" strace files? It is certainly possible that there is a bug as this 
functionality was not thoroughly  tested. I willing to fix it and help you with 
that. Your sample strace file + ignore/map files + arguments would help.

Cheers
