What's consuming the app server heap memory?

Question

Dear all,
I keep getting the "java.lang.OutOfMemoryError: Java heap space" error in our environment, I tried to remove the BAM from the Jboss, and the error disappear for some times, but it appear again recently, while we only changed one line of script in one of the form. (i.e. I don't think the error is caused by changing code)
So, I would like to know where can I find some information about how the memory is consumed in ALC? Because we only have 2 workflow running, although one of them is heavily used.
Here some information about my environment.
- ALC 8.2.1 with no sp
- Using the default Jboss as app server
- Using the default MySQL as Database
- Only 2 workflow running
  - While 1 of them have around 4 - 8 request pre week
  - And the others will have around 60 - 80 request pre day (i.e. around 490 pre week)
Here listed some points I think may affect the memory and I want to know for sure:
1) Number of variable used in long-live process (i.e. More variable = more Memory used)
2) Number of operation used in long-live process (i.e. More operation = more memory used)
3) Number of track record of long-live process (i.e. More track record = more memory used)
4) Long-lived process vs Short-lived process (i.e. Only long-lived process will keep consume memory because short-lived process will only load on call?)
5) Number of long-lived process still running (i.e. If we send a assign task to notify the user the workflow have been approved, and the user never dismiss it, it will turn out to consume the app server memory because it is still in the running stage)
6) Old version of the same long-lived process will use memory even no active workflow? (i.e. Because active long-live process will load up into memory?)
Thanks in advance
Regards
Bill

Did you tried to increase your heap size in jboss server . try this  and i think it will  help you in solving this problem .
if u want  to know how to increase the heap size:
go to bath of ur JBoss    "D:\Adobe\Adobe LiveCycle ES2\jboss\bin" as example.
scond find the Run file and  open it in  Text File
find a line  which is responsible for   heap size ==>>"set JAVA_HEAP_ARGS=-XX:PermSize=128m -XX:MaxPermSize=192m -Xms1024m -Xmx1024m"
close it and restart the server again and test your problem.
put ur line to be like what i wrote 1024 means that 1 giga for heap of jboss.
if the problem still appear for  you then your Memory doesnot of because memory heap size
