What do other people use as their memory limit for mongrel in monit?  
I’m using these settings below and it seems like I’m getting a lot of  
emails and restarts. Should I bumb up the totalmem limit to 80 or 100?

```
    if totalmem is greater than 60.0 MB for 5 cycles then

```

restart # eating up memory?  
if cpu is greater than 50% for 2 cycles then  
alert # send an email to admin  
if cpu is greater than 80% for 3 cycles then  
restart # hung process?  
if loadavg(5min) greater than 10 for 8 cycles then  
restart # bad, bad, bad  
if 3 restarts within 5 cycles then  
timeout # something is wrong, call the sys-  
admin

```
    if failed port 8000 protocol http
            with timeout 10 seconds
            then restart
    group mongrel
```

I’m using 70 and 90MB in two different apps. So far it’s been good for  
me.

I set the default memory limit to 110Mb on engineyard slices. Memory  
usage also varied on 32bit vs 64bit platforms. If you are on 32bit  
then mongrels use about 10% less emory then on 64bit servers.

Yeah, I’m thinking that 60 might be too small. I’ll bump it up.

[OT] This configuration I thought it isn’t very correct. Imagine if you  
disable your web application(for example with: cap deploy:web:disable)  
and then you make changes while monit is trying to restart mongrel it  
can be a bit annoying. Maybe will be put an “and not exists  
public/system/maintenance.html” (pseudocode not real code) 😉

Yeah, or you can disable the monitoring of mongrel before a longer  
change. I believe because all the mongrel checks have the group  
‘mongrel’ I can start/stop monitoring on them all at once without  
turning monit on and off.

We use a limit of around 110 - 130  
It really sucks as a solution though…
