Hi list,
in order to find out why Opera often keeps hanging (doing nothing),
often for several minutes, I checked its top(1) output.
Reading "man top", I found the following explaination:
[...] STATE is the current state (one of "START", "RUN"
(shown as "CPUn" on SMP systems), "SLEEP", "STOP", "ZOMB",
"WAIT", "LOCK" or the event on which the process
waits) [...]
When Opera just hangs(TM) :-), it is in one of the states "ucond"
or "umtxn" - and sucking up to 100% WCPU.
Here is my question: Is there an explainative list that gives a
clue about what this state indicates? Where are these "event[s]
on which the process waits" documented?
When I could guess, then I'd say that "ucond" means "unconditioned",
"in no condition" (which would be a very strage state - the absense
of any state), and "umtxn"... um... USB mass storage transmit number?
No idea.
Other states that I see have a more descriptive name, such as "pause",
"select" or "getblk" and even "kqread".
Setting: I have opera-9.63.20081215_1 on OS 7-STABE from August 2008.
Thank you!
