Demo Servers Down?

[Adrian Crum-2]

I get this error when trying to use the OFBiz demos:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, [hidden email] and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Yes it ran at 512mb out of memory...
increased memory to 768Mb and restarted.

this means however with the current memory of 1Gb can only run one
instance....

Hans

Hi Guys,

I just realised that on the new demo server the reports on this page
don't work as the DataWarehouse has not been initialised.

https://ofbiz-vm.apache.org/ordermgr/control/OrderPurchaseReportOptions?USERNAME=admin&PASSWORD=ofbiz&JavaScriptEnabled=Y

If the demo server has a full rebuild each night can initialising the
DataWarehouse be added to the list so that the reports work correctly.

Cheers
Sam

Thanks Hans,

I just visited the demo site and checked memory use - 384M had been allocated, with about 160MB in use. After running Artifact Info, 768MB had been allocated with over 600MB in use. I ran the GC and the in use memory dropped down to 393MB.

It's a nice thing to have, but maybe we should disable the ArtifactInfo screen on the demo server. I guess either that or we need more memory for the demo.

That would be a simple fix, but I would like to see what others have to say about the memory use.

The artifact info screen is a good "acid test" - since it touches nearly every artifact in the project. In other words, let's use it as a tool to spot weaknesses or memory leaks.

I'd start by doubling the memory - go to 2 GB for two instances - at least.  The server we were hosting at Contegix had 6 GB by the time we got comfy.

This would be better, but is it possible? Anyway we should ask infra with a Jira to know...

Thanks

That will probably just mask the memory problem. It will still go down
when people work their way through enough of the screens. What may be
more critical is to ensure that memory is being released (dereferenced)
more aggressively when memory gets tight.

Thanks Ean, that's what I meant to say but couldn't find the words. I wasn't finding fault with the artifact info screen, instead I was trying to say it is revealing a memory problem, so we should definitely keep it.

The thing with the ArtifactInfo stuff is that you're not lazy-loading any more, you're getting every service implementation, screen, form, menu, etc all in memory at the same time. Currently in OFBiz that's a lot of stuff and it takes up a fair bit of memory. It could possibly be optimized to use less memory for the same stuff, but one way or another it's a lot of stuff.

It still doesn't need to keep it all in memory.  The artifact stuff
scans everything, so it can populate a drop-down.  However, it keeps a
hard-ref to it while it is scanning, and that is what causes the
memory usage to balloon.

It keeps it for a little more than a drop down. Try trimming things out and see how the searching, reverse references, and so on are working afterwards.

Can it extract the data it needs from the entities and then release the
references?

Yeah, it doesn't need to keep a referenc to the entire widget object
graph, just the cross-references to each included part.
