Hi all, noticed this yesterday in the logs,

 

My understanding is it some kind of network monitor?

Does nethogs get any updates in the later versions of unraid? Am on 6.12.11

 

Cheers

 

kernel: traps: nethogs[12313] general protection fault ip:14af7e1d026c sp:7fffd3123e10 error:0 in ld-linux-x86-64.so.2[14af7e1c3000+25000]

 

The error you observed in the dmesg log related to nethogs indicates a general protection fault....

 

Understanding the Error

 

General Protection Fault:

A general protection fault occurs when a program (in this case, nethogs) attempts to perform an invalid operation in memory, such as:

Accessing memory it does not have permission to access.

Using an invalid or corrupted pointer.

Performing an unsupported operation.

 

The Error Details:

nethogs[12313]: This indicates the process ID (12313) of the nethogs binary when the error occurred.

ip:14af7e1d026c: Instruction pointer address where the fault occurred.

sp:7fffd3123e10: Stack pointer address at the time of the fault.

error:0: Error code. In this case, 0 indicates a general protection violation, often caused by accessing restricted memory.

in ld-linux-x86-64.so.2: The fault occurred within the dynamic linker (ld-linux-x86-64.so.2), which is responsible for loading shared libraries for the nethogs program.

 

Why This Happens:

Corrupted Binary or Library: The nethogs binary or one of its dependencies (like ld-linux-x86-64.so.2) may be corrupted.

Compatibility Issues: A mismatch between the nethogs binary and the system's shared libraries or kernel version can cause faults.

Bug in the Program: A programming bug in nethogs may lead to memory access violations.

Resource Constraints: Low memory or other resource limits can exacerbate such issues.

 

?6.12.11 please update to lattest stable release of 6.12.14

unraid had an update

what nethogs is:

kinda not realy a network montior per say it is a widnwos taskmanger like tool uses to look at current network traffic

 

NetHogs is a small 'net top' tool. Instead of breaking the traffic down per protocol or per subnet, like most tools do, it groups bandwidth by process. NetHogs does not rely on a special kernel module to be loaded. If there's suddenly a lot of network traffic, you can fire up NetHogs and immediately see which PID is causing this. This makes it easy to indentify programs that have gone wild and are suddenly taking up your bandwidth.

Thanks appreciate your insights.

Sounds like its a random event.

 

Had some problems with 6.12.12 (random crashes so reverted back to 6.12.11).

Have now updated to 6.12.14 & all seems stable.
