Re: How often do you bounce your apps?

[Stefan Gärtner via Webobjects-dev]

We never bounce, but every few weeks we have an update, which certainly starts 
a new instance.
We heavily use EOF. I never had the feeling that there is any memory leak, at 
least in our scenario.

Re: How often do you bounce your apps?

[D Tim Cummings via Webobjects-dev]

Daily for us. Once every few months we get an instance hanging and it is clear 
at the start of the day that it has hung because it hasn’t restarted overnight.

We don't bounce our apps unless we do a release or if there's an instance
that hangs.

Re: How often do you bounce your apps?

My apps upload pdfs. As Java keeps the temp file that was uploaded until the 
app that did the upload quits, I bounce my apps every night to clean things up.

 On the other hand, I could see an argument that a java app shouldn’t have

 cannot do so, then you’ve got something messed up in your app that you 
 should track down and rectify. So maybe it’s better to just leave your

 What does the community do? Do you cycle often (daily, twice per day, or 
 once per week) or do you leaving your instances running without a

Re: How often do you bounce your apps?

[Jesse Tayler via Webobjects-dev]

What do you use to keep an eye on memory? JAVA has such an old-school approach 
with the VM I use AWS and really don’t have any good automated visualizing 
report on how instances or JAVA is running under the hood.

My apps seem to run for a long time as a few times my scheduler has failed and 
they racked up 10X or even 100X normal sessions, but who knows what the user 
patterns were really — I have had to increase my JAVA VM and set memory stuff 
from JavaMonitor to keep things sane.

Re: How often do you bounce your apps?

[Jérémy DE ROYER via Webobjects-dev]

Hi Aaron,

(I’m still using EOF) and, for the main apps, I bounce every morning.

After updates I sometimes forget to activate the schedules without any 
problems… but I’m used to do it in the pasts where I had a lot of meomry leaks 
so I still do it.
