Tar seems >to be o.k. dump most time can recover (better survive) 2 hanging SCB! I am having a terrible (and probably similar) problem with dying dump on the HP C1533A DDS-2 drive and Adaptec2940 and FreeBSD 2.2.2. See log below, after that it just almost-hangs (IP and presumably other parts of kernel work, but nothing more) till RESET. It used to happen every several months but recently I had this during 2 unattended backups in a row (separated by 3 days). What I could do about this? Will upgrade to 2.2.5 help? (though back in 2.1.0 only dump sometimes crashed but not the system as a whole *-(( ) Thanks in advance Genie -- ######################################################### Eugene V.
