linux - lsof shows difference in open file descriptors in riak process -

-

when doing lsof -l shows open file descriptors (~180000), when checking lsof -lp pid shows ~1000. know process pid pid has ~170000 file descriptors open.

here logs:

root@riak:/proc/3238# lsof -l | grep 3238 | wc -l 172923 root@riak:/proc/3238# lsof -lp 3238 | wc -l 1075 root@riak:/proc/3238# ls -la | wc -l 44 root@riak:/proc/3238# ls -la fd | wc -l 924

why there such difference?

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
