Hi Norman,
I've set ulimit -n 65535 (default was 1024), used -Xmx512m (cfr your
last commit) and connectionBacklog=900
lsof -p pid| wc -l gives around 550 (stable).
No issue after stop (test with embedded Derby).
Disk swapping and exceptions came from the 64m limit if you don't set
-Xmx
Hi Eric,
thx for all your help and tests :)

Hi Norman,
Trying to simulate a more real-life test case, I developed a small
bomber class that launches parallel threads. Each thread sends mails
with attachements (with small pause between each mail sending).
I tested with embedded derby with JDBCDomainList.
Depending on the parameters
Hi Eric,
for such high load you will need to adjust a few things:
1) set a higher ulimit. By default its 1024 on linux which is prolly
not enough ( I use fbsd which use 11095 by default)
2) set a higher connection backlock in smtpserver.log

Hi Norman,
What do you mean with ...backlock in smtpserver.log ?

Hi Eric,
thx for your tests. The order of the uid is caused by the threads,
thats nothing to worry about.
About the timeout, can you try to add this to the test case:
properties.put(openjpa.LockTimeout, 3);
And keep in mind that we don't use any connection pooling in the test
case so the
Hi Norman,
Similar exceptions with properties.put(openjpa.LockTimeout, 3);
I think the environment simply can not follow the load (more than one
mail sent each ms).
Bootleneck can be anywhere (connection creation, database lock,
openjpa,...).
This is why I put a sleep between each mail
About 6000, then I run out of heap space..
Can you maybe try to deploy it with james and bomb it via smtp ? I was
not able to see any exception.
Thx,
