Re: [Wrapper-user] problem with java service wrapper

[Alexandre K. <ale...@ta...>]

Hello,

Thank you for your email.

As you could see the Wrapper works as expected by detecting the string
"java.lang.OutOfMemoryError" and restarting your application.
Unfortunately, in your case, there is a kind of false-positive action
triggered because of the following line:
- KEY(index=8 name=REMARK type=12 [VARCHAR] length=512 unsigned=false
blob=false desc=VARCHAR(512)) = java.lang.OutOfMemoryError: GC overhead
limit exceeded

To solve that kind of situation, you can create a filter to catch that line
and do nothing. A line can be filtered only once, so the Wrapper will not
apply any other filters.

For example:
wrapper.filter.trigger.1=KEY(index=
wrapper.filter.action.1=NONE

wrapper.filter.trigger.5=java.lang.OutOfMemoryError
wrapper.filter.action.5=RESTART
wrapper.filter.message.5=Replicator ran out of memory, restarting

Now the line will be filtered by the filter #1 and your application will
not restart.

I hope this will help you solve your issue.

Please let me know if you have any other questions.

Regards,
Alexandre Klein
