Thanks Kieran,
I might have to take you up on that. I've been thinking that it must
be something to do with too many records been read in but I can't see
where that could be happening.
I'll try adding the encoding string to the EOModel connection and see
if that helps. I've just tried changing back to the old adaptor but
doesn't seem to have helped either.
Regards,
David.

Hi again David,
Regarding App Oout of memory:
App out of memory commonly is caused in WO apps by reading in too
many EOs (display group or possibly a huge faulted relationship) or
too many concurrent sessions and needs profiling or at least
strategic logging to see what is happening in production. If the
problem can be simulated in development environment, it will be
easier to resolve. Wonder has some features that allow free memory
tracking, memory reserve, temporary refusing sessions in low-memory
conditions and forced garbage collection.
To give you breathing room to troubleshoot you should have maxed out
memory per instance. I think 1536 is the max for 32-bit system, so
WOMonitor args should be sth like this:
-Xms1024m -Xmx1536m
I am very tight on time myself, but if no one offers to get their
hands on to track this down in the next 24 hours, I might be able to
help tomorrow (Friday) .... let me know if that is the case.
Regards, Kieran

Hi all,
I've been having a real problem over the past 12 months with my
WebObjects and mySQL installation. It has been getting gradually
worse to the point now where the apps crash every 10 or 15 mins.
The are crashing out with Java.OutOfHeapSpace errors. We've tried
everything to increase the heap space but has made no difference.
The fact that it is has gradually gotten worse over time indicates
to me that as the database is growing the problem is getting worse.
I tried last night to update the Connecter/J adaptor to version 5.1
as we were using an older one and I thought that might help. It
hasn't in fact, and what it has done is make all the € symbols
appear as '?'. I know this has to do with the encoding and I want
it all to be UTF8 but I can't seem to work out how the hell to get
them to display properly. They all displayed perfectly before I
changed the adaptor.
On the other hand, I really need to find a solution to this problem
where the apps are crashing and I am very tight for time. I am
prepared to pay someone to track down this problem for me. Any
takers?
Kind regards,
David. _______________________________________________
