unitronics PLCs support modbus over serial and TCP/IP on ethernet. use the mango modbus data source.

Phil,

I restored all of the incrementals up until the deletion occurred since everything since then would be stored on the ES devices we've deployed so I wasn't worried about the most recent stuff.

I did not attempt what you suggested since restoring them one at a time worked. After restoring around 10 I would run in to a concurrent error. I would reboot and then pick up were I left off. Everything seems to have gone well and I don't appear to be missing anything.

Thanks for your help and suggestions.

Ok after reading trough those posts, I can see that mine happens about every 12 hours, but I don't know what tasks I've set (if it was me) to occur every 12 hours. Either way, if it's not a big deal then I'm not worried.

Thanks for sharing the resolution!

Most welcome. Also, I had to edit my script... tis "detectorXID" in the point event handler object.

Hello again!

Thanks for your fast response. I tied your proposal. Success! If all points are set to " Do not log" I still get the "0x0" so I tried set points to log and the Data source to not log anything and the fail disappeared. Now i can see other problems diving up in an reasonable way. I will continue my investigation what are causing the problems. Possibly its due to bad wiring or severe disturbances from source.

Will post later what finding I get.

Thanks again.

Hi ray,

You're correct. I took a quick peek at the history of the code producing that chart, and didn't find an obvious culprit. So, I've created a git issue for this: https://github.com/infiniteautomation/ma-core-public/issues/828

Thanks for letting us know.

uhhh... yeah. I knew that.

;-)

Hi Phil,

There are no hs_err logs in my MangoES instance after changing the meta datasources like you instructed. The system was stable for a while but then switched off and a manual restart was needed to get mango up again.

As I was checking what may be the cause I found out that using concurrent-carbage-collector to free some memory space was the reason for strange behaviour in the system.

The average uptime was still around 3-5 h.

After removing the CGC the system went stable and then I noticed that there is a memory leak somewhere because right now the system can work around 20 h and then reboots.

The memory usage at boot is around 1 gb and starts growing until Mango reboots. Probably because system kills Mango as it is taking so much memory and then the check.sh script reboots MangoES.

As i understand that removing the CGC set me up with the default GC algorithm but I can't seem to notice if the GC on Mango is freeing up my memory or not.

Its a problem because I think ideally MangoES should be running for days/months without interruption.

I have another MangoES in my office running now 3 days straight without problems. Of course it is just a clean out of the box with only System Information datasources activated. But this instance will be going to our clients also next week with a similar system installed on it as the one which I am having problems with.

Many thanks,
Thomas

Unfortunately there is no way.

You can also do it from the SQL console, try this
DELETE FROM pointValues WHERE dataPointId NOT IN (SELECT ID FROM dataPoints) LIMIT xxx

Terry,

Thanks for the tip on:

runtime.realTimeTimer.defaultTaskQueueSize

The setting was adjusted to a max of 2. The FATAL message still occurs. Periodicity is around a minute between occurrences. It seems better than it was but still nagging away.

If you're not seeing the same thing on your end there must be a configuration difference on my end. Dealing with configuration problems is tiresome for all involved. With that in mind, I highly recommend Docker. If Mango were available on the Docker hub I'd definitely use it.

Solved.. Thank you all

@terrypacker
Thanks Terry, I look forward to the feature making it in!

Joel, We were converting from H2 to MySQL. That was the time from shut down to restart. I have checked the data points and all seems fine at this point.

I try the new data file module. It does not work.

I am trying to connect to the h2 server DB with "Razorsql" ,but it tells me ------
((ERROR: An error occurred while trying to make a connection to the
database:

JDBC URL: jdbc:h2:P:\IT Dept Installs\Mango Automation 2.7.10
Enterprise Demo\databases\mah2

Database may be already in use: "Locked by another process".
Possible solutions: close all other connection(s); use the server
mode [90020-166] ))
Has any one used razor for the h2 DB? Any help would be great. Thanks

Looks like you don't have any Modules installed. Go to the Modules page and click "Check for Upgrades" then expand the list of Modules available for installation and check the ones you want.

Thank you
