Hi there ppl, here I am again with the old problem - random system locks ( approx. once in a day or two) on loaded system. The good news is: The QUOTAs code doesn't lead to kernel locking ! - albeit the premonition a few ppl here had ( me incl. :). Something else causes the locking . Very interesting one IMHO - the console driver is alive ( you can switch the virtual screens from the console) , the ping from remote sites works too , when one tries telnet or ftp tp the hung host - it does say "connected" , but that's about it. You can't get anything else ! I don't know if this description in enough for some1 here the reason/cure , but hey , you never know ! :) The system is : P90 , 128Mb RAM, Bustec 946C PCI-SCSI , 2 HDDs Seagate Barracudas. The locking happens on different systems ( 4 of them) _regularly. The motherboards are different , on some systems there is Adaptec 2940 instead of Bustec. I'll try to compile DDB support into the kernel and produce more detailed description of the problem later .. Rashid PPS Assuming this problem will be fixed I think that the 205R could be used in server config as fast and reliable alternative to SSs :)) Any cure? Rashid
