Hi List, I am running a couple of dd processes on the scsi drives on ia64 running 2.4.2 kernel. e.g. while [ 1 ]; do dd if=/dev/zero of=/dev/sdb1 bs=1024 count=25000000 done & while [ 1 ] ; do dd if=/dev/zero of=/dev/sdb2 bs=1024 count=25000000 done & while [ 1 ] ; do dd if=/dev/zero of=/dev/sdb3 bs=1024 count=25000000 done & What I have observed is whenever one of the dd processes completes and starts another process ( because of while [ 1 ] loop), the system freezez. I have no idea what is going on. In fact I tried this on ia32 system as well. On ia32, I see lot of delay before I see any activity on the disk and during that time system freezes and I cannot do any thing. Well, on ia32 finally the system comes back up. But on ia64 the delay is very huge and sometimes the system does not come back up even after many hours (even after leaving the system overnight). Has anybody seen this problem ? Does anybody know what the problem is ? I need to have solution for this problem ASAP. Please help me out.
