Hi! The problem: The "father" process of my samba server is core-dumping "spontanously", normaliy after several hours (12 typicaly) of smooth running, resulting in new requests beeing rejected. All the existing sessions and assosiated "child" processes survives, but "fatherhood" is passed to the init process. The background (not the issue): We have experienced hangs on our system leaving top display with several hundred processes in "WAIT" state. We have seen the system resolve the problem, which involv moving all the "WAIT"'ing processes to "run". This takes so long that in workhour we prefer forcing a reeboot. Our current theory is that the hangs is caused by our Raid controller under heavy load. The issue: Is there a chanse these problems are related: Is our IO problem generating the recursion? Does the "adaption" of childs generate activity in them? Sorry for the size of this mail. It was intended for samba-bugs@samba.org, but they seems to have "hung up". I know the problem: To get things done - ignore the phone... TIA BT. OS: Compaq Tru64 Ver 5.1 in cluster environment. No enhanced security. Load: average 400 processes, 500 connected services.
