NetXMS Support Forum

Hello

We are experiencing with crashing netxms after the upgrade to 1.2.17. This generally happens after 10 minutes of loading, setting up the server for CrashDumpLog does not produce a log file for program crash. Running the server with debug mode 9 also does not give any clear indication before netxms stops. We have currently tried this on a windows instance and on a linux instance, both appear to have the same issue. The only current indication of issues are from;

We have made no amendments to the Database structure. Deleting the content of the alarm_events table completely makes no difference. 'nxdbmgr check' passes all the current checks.

Not to sure what the next step should be. Not particularly clear how the BIGINT is shown as a hyphenated number?

Hi,

if you have Linux installation, can you please run it under gdb?

Commands would be like this:

gdb /path/to/netxmsd

will show (gdb) prompt, then

run -D5

server will run in foreground. When crash will happen, (gdb) prompt will be shown again. Type

bt

and send me an output.

Best regards,
Victor

Hello

Found a core dump for which I have a backtrace of, awaiting the gdb version to run and provide a live version;

Summary look at the node does not imply any particular issue;
Seems to be un-connected with the other SQL errors which are happening -D5

Hi,

it's a bug that is already fixed in development branch (will be released as 2.0-M1 soon). In the meantime you can patch server code manually if you are building it from source:

In file src/server/core/node.cpp find line


             Node *peerNode = (Node *)FindObjectById(iface->getPeerNodeId(), OBJECT_NODE);


(should be around line 5329). Immediately after that line add the following code:


            if (peerNode == NULL)
            {
               iface->clearPeer();
               continue;
            }


Best regards,
Victor

Thank you,

Will apply the fix now.

Regards

Aron
