I am currently using Mesos + Marathon with 4 slaves for the test. When I launch a lot of tasks with command ping 8.8.8.8 or while true; do sleep 1; done;,
at one point, slaves cannot launch a task any more. The states of tasks that are newly launched are 'Failed'. So I checked out stderr of sandbox, then it shows "Failed to initialize, pthread_create" I launched tasks with 0.00001 cpus and 0.00001 mems, so enough resources to launch a task remained in slaves. In a slave, ulimit -a shows *# ulimit -a* core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 1545932 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited *open files (-n) 65535* pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited *max user processes (-u) 1545932* virtual memory (kbytes, -v) unlimited file locks (-x) unlimited Is there any limit of the number of tasks that can be launched by Mesos on a slave?
