<div>Hello,</div><div><br></div><div> I gave up of using syncop calls at my attempt of copy a file to a local node while the read is happening (at each readv_cbk in this case)... it was failing often and I could not benefit from the frame->local isolation between the readv/readv_cbk/<syncop calls> because the local context was lost when inside the function called by synctask_new.</div>
<div><br></div><div> Anyway, I built a logic with wind/unwind calls instead, and I am getting a strange fault to begin with, out of my translator. At the readv_cbk() I am calling xl->fops->create with most of the parameters I was using with syncop_create (the fd, loc, flags, etc were created and populated locally while in the readv_cbk), but the execution is stopping at the path below because the <b>myframe->local is NULL</b> and the fd cannot be gathered <b>at client3_3_create_cbk().</b></div>
<div><br></div><div> <b>At the backend the file was created</b> (but not yet populated or set with attributes). </div><div> Does this kind of behavior is known, a bug for an unusual scenario, or what I am missing here?</div>
