With the trivial fix to patch 5 I sent earlier, I've been running the following e2loop.sh for a few hours with no problems (the counter is at 2412). Also did 500 concurrent checkpoints of the same process. Oren, can you re-post an updated patch 5? Andrew, would you mind (once Oren reposts patch 5) giving the first 11 patches a chance in -mm? thanks, -serge =============== e2loop.sh: =============== cnt=1 /usr/src/ns_exec -m /root/e2 & while [ 1 ]; do /usr/src/cr `pidof e2` o.$cnt kill -9 `pidof e2` echo 5 > /root/e2out cntin=`cat /root/e2out` echo "i reset e2out to $cntin" #/usr/src/rstr < /root/o.$cnt & /usr/src/ns_exec -m /usr/src/rstr /root/o.$cnt & cnt=$((cnt+1)) sleep 10 cntin=`cat /root/e2out` echo "cnt is $cnt, e2out has $cntin" done =============== e2.c: =============== #include <stdio.h> #include <sys/types.h> #include <unistd.h> int main() { int cnt=0; FILE *f; char fnam[20]; close(0); close(1); close(2); close(3); f = fopen("e2out", "r"); if (!f) cnt = 1; else { fscanf(f, "%d", &cnt); fclose(f); } for (;;) { sleep(5); f = fopen("e2out", "w"); if (!f) return 1; fprintf(f, "%d", ++cnt); fclose(f); } return 0; } _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
