sage sometimes leaves matlab processes that eat 100% cpu time
|Reported by:||cwitty||Owned by:||was|
I've found a way to somewhat reproducibly leave a matlab process eating 100% cpu time.
I log on to sage.math, start Sage, and run the following commands:
sage: m = matlab(matrix(RR, [])) sage: m.det()
Then I kill my local ssh client with "kill -9" (to make a non-clean ssh shutdown).
Often (not always, but I think more than half the time) this leaves a matlab process eating 100% of the cpu time.
