Well, there's no way I'm dissecting mine, but Wikipedia says both units
have 128MB. Are you talking about "two 512 Mbit SRAM dice"?

That's interesting, and implies that apps that care to manage their own
memory could be HUGE in terms of code size. I didn't realize the level
of customization and specialization that had gone into the iPhone's
version of OS X. Do you have a reference I could see?

Looks like the true RAM on the iPhone is indeed just 128 MB, embedded in the same chip carrier as the ARM processor; here's the data sheet for it:

No, what's been reported on various mailing lists.

Again no, sorry. Just browsing lists after I bought one. As I said, it's hearsay.

Do you know what precisely was done via the Tomcat manager?
You say "the log", but there are numerous log files produced by Tomcat and various webapps; you really need to look at pretty much all of them.
By any chance, does your webapp spawn extra threads, and not shut them down properly? Does it use any native libraries?

Please forgive my foolishness as it is Friday afternoon and my brain
must already be on weekend.:)
Tomcat=6.0
Java=1.6
Redhat Linux 3.something.

How about looking at the Tomcat version, JRE/JDK in use, OS, etc. - and
then telling us what they are. Or consult a psychic.

Management app start
Posted by "Hehl, Thomas" <Th...@acs-inc.com>.
I have a client using our software and have set up for them a user for
the management app. They brought up the management app and stopped the
webapp, but cannot seem to get it started again. I had them e-mail the
log, but no help.
This is a remote client, so I'm stuck as to what to look at next.
