It looks it is being killed right after matching the limit not respecting the 8
cycles. defined as individually below
```
check process unicorn_master_teachworks
with pidfile /var/run/engineyard/unicorn_myapp.pid
start program = "/bin/bash -c ‘/service/bin/app_myapp start'"
as uid deploy and gid deploy
stop program = "/bin/bash -c ‘/service/bin/app_myapp stop'"
as uid deploy and gid deploy
if mem > 350 MB for 2 cycles then restart —> Is this group directive
overwriting the individual one below?
if cpu > 100% for 2 cycles then restart
group unicorn_myapp
check process unicorn_myapp_worker1
with pidfile /var/run/service/unicorn_myapp_worker1.pid
if mem > 350.0 MB for 8 cycles then exec "/bin/bash -c '/bin/kill -TERM `cat
/var/run/service/unicorn_myapp_worker1.pid` && sleep 1'"
group unicorn_myapp
```
Thank You,
