Dear managers,
currently we are being tormented by system crashes that are reliably deducable to the invocation of certain dbx commands (!).
Basically, the crashes occur, when you do a "dbx -pid ...", define a certain breakpoint, issue "cont" and, when having reached the breakpoint condition, "S"tep one instruction forward.
When such a crash first occurred, we had a we had a "good" crash with information in uerf-Log, /var/adm/crash and so on. Later "bad" crashes just halted the machine.
Anyone having experienced similar problems / able to offer advice?
