- We don't see hangs; what we see is an occasional interactive program
- looping to beat the band. Since upgrading to 3.2.1 (later to 3.2.2)
- we have seen the following programs looping:
- vi aixterm less info_ascii
- and maybe a few more I forget. The typical scenario is the user
- telnet's in, works away, and for some reason has the session broken
- (who knows, maybe after something hangs) after which s/he logs in
- again, or goes to some other work, unaware that one of his/her processes
- is running amok. Since we have 18 550 cycle servers to
- look after, some of these runaways chew up quite a bit of cpu time
- before they get killed by a system administrator. I have vague
- suspicions of (a) the telnetd, (b) something in the way these programs
- handle signals or system-call errors, (c) [the ever popular] AIX.
-
- Anyone have similar experiences, or ideas about the cause? Are the
- above fixes likely to help us?
-
- Thanks.
