Hi Elvin, Then this is a bug in the client. I had a long discussion about this with Lukasz. The final implementation was supposed not close the TCP connection if there was an outstanding response. This, of course, does not apply when the server sent a simple "wait" as there is no response outstanding and the request can be resent after the wait interval. This is not the case with "waitresp" as that implies that the response will be sent later. The endsess failure indicates that there was atleast one request still active when the connection was closed. So, this is indicatve of an error. Of course, loosing the opaque information on the retry is another problem. BTW does Castor send waitresp responses (i.e. the ofs plugin returns SFS_STARTED)?
