I think our shortest timeout is 10s right now so this should work. I would suggest aborting the command if you see enought HTH timeouts to be roughly equivilent to the timeout value in the xfer or if your timeout handler is called. This would give you all the information you have now, but a longer (tunable) timeout. >Regards, STefan >-- > Stefan Esser, Zentrum fuer Paralleles Rechnen Tel: +49 221 4706021 > Universitaet zu Koeln, Weyertal 80, 50931 Koeln FAX: +49 221 4705160 > ============================================================================= >= > http://www.zpr.uni-koeln.de/~se <se@ZPR.Uni-Koeln.DE> -- Justin T.
