Occasionally my unraid server will become unresponsive and freeze up. This maybe only happens once few months and the only was to fix it is to hard shut down by holding down the power button and turning it back on again. If anyone is able to take a look at the logs and find out any clue as to why this is happening that would be amazing. I have not been able to figure out why. The freeze happened last night May 13/14, it could've frozen anywhere from around 10:00pm to 7:00am. I have attached my diagnostics, and a syslog that covers that period of time. Thank you and let me know if there is anything else I can provide. justinserver-diagnostics-20260514-0851.zip syslog-127.0.0.1.log

Yes I do, they are sprinkled throughout the logs. They don't seem to correspond to crashes from what I can tell. This is one example of what it looks like for me if it helps.

Hi everyone, I have been running this minecraft server for a few weeks now for just 3 people, nothing too intensive, but I am getting random JVM crashes that result in disconnects and progress loss. This is the error message that appears in the logs. I am running Minecraft 1.20.6 # # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x00007f72d8155213, pid=152, tid=220 # # JRE version: OpenJDK Runtime Environment (22.0) (build 22) # Java VM: OpenJDK 64-Bit Server VM (22, mixed mode, sharing, tiered, compressed oops, compressed class ptrs, g1 gc, linux-amd64) # Problematic frame: # J 37491 c2 bxo$$Lambda+0x00007f7273d96f58.trigger(Larf;Lbtr;J)Z (38 bytes) @ 0x00007f72d8155213 [0x00007f72d8154f40+0x00000000000002d3] # # No core dump will be written.

If anybody is able to help me out that would be a great help. Thank you
