Re: JobInvoker crashes while reading serviceengine.xml

Sat, 27 Feb 2010 03:43:05 -0800 

Hello Adrian,

No, I did not touch the content of that xml file. It is the original one.
Right now there is a shell script watching the log file. If it encounters that error I clear the cache you recommended. 
How can I help you identifying/reproducing the problem?

regards,
Florin

Florin,

I have been unable to duplicate your problem. Have you changed the contents of 
serviceengine.xml? That is the only thing I can think of that would cause the 
error message you are getting.

Florin,

Thank you for the information. I believe there might be a
problem in the way things are cached. I will look into it
further.

For now, if clearing the cache solves your problem then go
ahead and do that. The long term solution will be to find
out what is causing the problem and fix it.

Now I can confirm it fixes the problem. While I do

that clear cache for resourceLoader I get few lines similar
with the ones mentioned before, like

2010-02-23 21:27:09,238 (default-invoker-Thread-498)
[ JobInvoker.java:267:ERROR] Problems 
reading values from serviceengine.xml file
[java.lang.NumberFormatException: null]. Using defaults.

BUT the main advantage is that server does not fully

crash and it recovers well. I do those calls on regular
bases every 10 mins..

I only ask myself if (depending on the number of

concurrent users) it needs to be done more often?! Could
reach other side effects by doing it more often?

Best regards,
Florin

I still need to know if that fixed the problem. If

it did, then we need to look into it further to get it
fixed.

Hello Adrian,

Many thanks. Now I have the first feeling that

it really helps!

It can be checked only in the evening because

during the day I am doing clear all cache on regular basees
for other other reasons (external process making updates to
products and lucene index)

So now I did it manually, I need further to

integrate it into a cronjob doing it every 30 mins maybe

Many thanks,
Florin

Florin,

The next time you have that problem, try

clearing the "resource.ResourceLoaders" cache and see if the
problem goes away.

Hello all,

I think I tried before to ask that

question, but I would retry because it becomes a critical
issue in production.

The Ofbiz instance runs fine for

several ours and unexpectedly I can see these lines below in
the log file. As soon as it starts with those exceptions, I
need to restart the instance because nothing works further.

I can say that I never developed any

additional/new Ofbiz Job and I also stopped some of them
which I was sure that are never used for my purposes.

I also tried to upgrade the parser,

but nothing helps by now:
