100% cpu

[Lares]

Witam i mam do was można powiedzieć 2 pytania.

1. Czy znacie jakieś sposoby obciążenia momentalnie cpu na 100% w tfs 0.3.6pl1? Ponieważ tak dzieje się na "moim" otsie domyślam się że może to być spowodowane skryptami ale na serwerze jest taka ilość skryptów że aby je wszystkie sprawdzić lub dodać printy aby w konsoli wyświetlało się który skrypt jest uruchamiany i który zjada cały cpu to musiał bym poświęcić na prawdę dużo czasu. Stąd moje 2 pytanie czy da się jakoś zrobić aby w konsoli wyświetlało które skrypty są uruchamiane bez potrzeby w każdym wstawiania printa (lub jakiś podobny sposób).

gprof prawde Ci powie.

Mozesz tez w momencie 100% podpiac gdb pod proces i zobaczyc co sie dzieje.

A coś dokładniej z jakim parametrem uruchomić gdb i na co zwracać uwagę? Nigdy jeszcze tego nie robiłem ale z miłą chęcią się nauczę.

gdb theforgottenserver pid

nic szczególnego nie wyskakuje więc domyślam się że robię to źle.
