SqueakMap dead?

Wed Nov 24 20:42:20 UTC 2004

By the way, related to this:

I didn't put two and two together initially but it occurs to me that
before I initially restarted it I noticed that the load on the server
was very high.  I failed to check fully but I suspect the SM process had
the CPU pegged.  The most common problem by far is a problem that
appears to be related to saving the image segments.  I think gokr has
speculated that it is a conflict which can occur if image segment saving
is taking place and someone tries to change something at the same
moment.  At any rate the fact that the load was so high indicates to me
that the SM process may have been in an infinite loop.  Said loop would
seem to be involved in image segment saving.  Whether there is a bad
situation in general that can lead to an infinite loop when trying to
save an imagesegment or if it is a result of data being modified while
said is going on, I don't know.  Anyway, just wanted to state my
thoughts on the matter.
