I am seeing this in Mirth version 4.1.1, 4.3 and the latest version 4.4
Please let me know how to resolve this issue.
Has anyone else experienced similar error

[pacmano1]

You should provide more context. When/where does this happen? Screenshots?

What java version on your local workstation andt the server?

Please don't post error messages alone, provide details.

Hi pacmano1,

it looks like this:

I have the same issue with version 4.4.x when the client is running longer time.

[tstac0427]

When this happens - I do not have exact timings but we have seen this 3 times in a week
Where it happens - Do you mean Test environment or Production ? - It happens in PROD, have shared below the prod server configurations
Screenshots - I do not have one at this point but will capture it when it shows up again, just noted down the error

Server 1
Java version - 8
Mirth version - 4.3.0

Server 2
Java version - 8
Mirth version - 4.1.1

Server 3
Java version - 15
Mirth version - 4.4.0

Where it happens = presumably on the mirth admin tool console log? The java console? A popup?

[kirbykn2]

Could this be a client side issue? What JRE are you using? What are your settings for the MCAL?

[tstac0427]

the popup is coming in the mirth dashboard.
We are using open source JDK as I mentioned the java version 8, jre version 8 and where Java version is 15 we use JRE 15.
What is MCAL ? Could you please elaborate

Does this answer your question on JRE?

[pacmano1]

MCAL = Mirth Connect Administrator Launcher.

[tstac0427]

this is the screenshot for one of the server MCAL

On this server mirth connect uses Java version 8 (open source JDK)
All 3 servers are Windows based.

[kirbykn2]

For funzies, assign more memory to the heap space, and try it again. Do you have customer libraries loaded in Mirth connect?

[tstac0427]

On Server 1 we do not have any library
Server 2 - has a custom library
Server 3 - does not have any library

Hi, What is the solution to the above problem as even I am facing the same issue. The error gets resolved only when Mirth is restarted.
Is there any solution for the issue? What is causing the issue in the first place?
I am also following https://forums.mirthproject.io/forum/mirth-connect/support/183947-stackoverflow-error

Same thing here...
Emptying the Java cache also appears to work, but only temporarily.

After updating from Java 8 to Java 21 (used by the server not the MCAL) on our test server I didn't get this error anymore till now.

[puresimmer]

Did anyone ever find a definite answer to this?

Thanks!

[JoeFox82]

After updating our servers to Java 21 (used by the server not the MCAL) I didn't get this error anymore. Tested with the Mirth versions 4.4.0, 4.4.1, 4.4.2 and 4.5.0

[prc9584]

I started seeing this when updating devices to 4.5.0, and have seen with both java 8 and java 17.

[prc9584]

Java 22 24 hours of monitoring and still no new StackOverflowError errors occurred. Will write a note if anything changes, but so far looks like a good correlation of at minimum java 21 to be installed to not get the errors indicated at the begining of this thread.

[prc9584]

Error came back over the weekend. No changes done on server.

[JoeFox82]

Today, one of our customers said, that he has the same error with Java 21.0.1 and Mirth 4.4.2. We've updated to Mirth 4.5.0 and now we are waiting if the error happens again. If it will happen again I'll try to update to Java 21.0.3 because Java 21.0.2 has two AWT fixes: https://www.oracle.com/java/technologies/javase/21-0-2-relnotes.html

[prc9584]

@JoeFox82 did you have any luck? Still seeing the issue on 4.5.0.

[JoeFox82]

After we updated the customer's Mirth to 4.5.0, the error no longer occurred. Java is still installed in version 21.0.1.

Edit 1: It happend again this morning.
Edit 2: It also happens with Mirth 4.4.2 and Java 21.0.3
