Hello, following the example of /sys/lib/lib9p/ramfs.c, i have done an fs test that dies unexpectedly with no error message, just " i/o hungup channel " because the proc died. i know about memory leaks in there, and i'm trying to found them with leak, but the proc dies just after running leak -s. how can i debug that? i shoud attach acid the first, and then run leak? thanks
