Benoit,
Thanks so much for the information. This has definitely been a
frustration. I'm glad that there is some hope at getting around it.
You mentioned a SizeGreaterThan matcher. Two questions....
1) How can I determine the threshold/limit size? I don't want to kill
off good emails just because they are a bit large. But I want to
definitely get rid of the ones that are causing the problem.
2) If I do get a hit, what processor do I call that will discard the
email and not risk further processing that might still cause the OOM?
Thanks again for the help.
Jerry

Hi,
You are processing a too large email. SetMimeHeader mailet is modifying
your email, but fails allocating more resources.
This may be caused to a missing pre-allocation parameter in
ByteArrayOutputStream. This sounds from the stacktrace like a limitation
of the javax implementation. (You might get very long headers on this
mail, I guess)
We had some recent work with javax, and it might be interesting to know
if this limitation is still here.
You get the error on a recurrent bases as James is marking processing as
failed and will re-attend it. You might want to position a
"SizeGreaterThan" matcher to defend against this.
Hope this helps,
Thanks for the report,
Benoit

I have James R3B5. It's been working fine for over 2 years. But in the
last few months I randomly start getting repeated OutOfMemory
exceptions. The only fix I've found is to delete the var folder and
reboot. The OOM entry in the log is always preceded by an error related
to one particular email. The error and an OOM repeat continually for
that email until I delete the var folder.
Since it will sometimes go a week or two without an OOM and then for a
few days it will happen every few hours, I'm pretty certain is has to do
with some specific spam message coming in that JAMES is not handling. I
don't know enough about the inner workings of JAMES to interpret this
stack trace. I can make a patch and rebuild if I can just figure out
where to patch a workaround for this. Can someone point me in the right
direction?
Log file: (this block is replicated 20-25+ times in the log file for the
same msg id; Looks to me like the camel processor is in an infinite
loop until OOM occurs)
BTW... my heap is now set to 1024m. I kept increasing it hoping for a
change. But it looks like its going to fill up no matter what size I
make it.
