[Issue]Uncaught Java.lang.outofmemory error

[DadalorianCreates]

Brief Description *

I installed the BPL Snapshot MegaMek , updated to the correct version of Java,. It ran just fine for two weeks. Now when I go into select units, if i select a unit i get "Uncaught Java.lang.outofmemory error". I discussed it with @Laura, she had me look at -Xmx4096m. It was set correctly. She referred me here.

I just tried to open MegaMek and it now gave me:
Error: Could not create Java Virtual Machine
Error: A fatal exception has occurred. Program will exit.

Note: i joined the MM Discord, but it is not allowing me to Post.

3. Steps to Reproduce

Original error:
1: Opened MegaMek
2. Started a game against Princess
3. Opened Select Units
4. Any mech i choose, does not select, does not display the record sheet and generates the outofmemory.

Unable to duplicate.

1. Are you using the EXE or the JAR?
2. Is Java 17 installed CORRECTLY?
3. How much RAM do you actually have?
4. How did you launch MegaMek? Directly or through MekHQ?
5. Have you re-installed Java from a clean slate?

I did when I first got the memory error. Should I try again?

What ever this issue is, it is on your machine. The best place to get support like this IS on the Discord. If you couldn't type anything on the Discord after joining, you'd do well to double check the on boarding process to see if you unintentionally disabled yourself within the Discord.

The above 5 items would still need to be answered before anyone can give support as each one can produce different kinds of errors.

Apologies for my lacking response earlier. I was dealing with a six year old and packing my house. 1. From EXE I get the 2nd error - the virtual machine one From JAR, I get the memory error 2. Yes and MegeMek was running fine for two weeks 3. 16 gigs of Ram 4. Through MegaMek directly 5. Yes, I did that when the error first occurred. I will sort my discord issues and ask there

I had the same problems with my first MegaMek install. I did install the 32-Bit Java Version
make sure to use x64 and not x86

Your log has the issue as it is your system. It can be the Java version or the way the VM is setup.
