Daily transactions for data updates and searches cause the freeze. JBOSS 4.0 web server and sometimes whole server needs to be restarted to fix the freeze.

Following generic message in server log is found:

Unexpected Error
java.lang.OutOfMemoryError: Java heap space

Overall server's health look good.

Try increasing your heap size from the command line:

java -Xmx<size>

for 2GB, you would use:

java -Xmx2g

Thinkspace is on the right track with increasing the heap size, but your problem may go deeper than that.

You may have a memory leak somewhere, or you might just be using too much memory, who knows.  Without more of an error stack or log, there's no way for me to tell you.

One thing I've seen before is when people write a SQL query so that it returns an entire table instead of just the row or few rows it needs.  Over time, the table grows and eventually gets too big to fit in memory - and causes crashes.  Coding like that is lazy, but it happens surprisingly often.

Though LiveCycle 8.2.x is no longer supported, you could update your install to 8.2.1.3 if it isn't already there.  You can contact Adobe to get the service pack, they should still give it to you.

What Is Threat Intelligence?

Threat intelligence is often discussed, but rarely understood. Starting with a precise definition, along with clear business goals, is essential.

Is there a way to seamlessly upgrade from 8.2 to Adobe LiveCycle ES4?

Direct upgrade to LiveCycle ES4 from 8.2.1 is not supported.

Does it mean complete re-write of the application?

It is correct that direct upgrade from ES 8.2.x to ES4 is not supported, but you can upgrade to ES2 and then upgrade to ES4.  So you can get there.

When you upgrade you will need to go through your applications because the model changed from ES to ES2.  You could continue to run things in compatibility mode, but I'd recommend against that - as soon as you need to make any changes, then you'd be upgrading your processes on the fly, and it's better to do it when you have time.

You should read this PDF for the changes from ES to ES2 - once things are running in ES2 they will move to ES4 without difficulty:
