<![CDATA[Server crashes after a few minutes]]>Hi,

now I have a big problem with netxms...

I made some changes to devices. Deleted a few, changed the snmp community on some others and changed the default community in discovery.
Suddenly the server crashed, means the service stopped.

Now when I start it again, it runs a few minutes and then crashes again.
I test now with a disabled Active Discover

Any ideas what I can do?

NetXMS 0.2.21
75MB MySQL Database

update:

Discover found the new devices at about 8 pm.

queues at the moment (still increasing):
netxmsd: sh queue

Configuration poller             : 0

Routing table poller             : 0
Status poller                    : 0

I created the dump, but I think you can see all the devices and related community strings in it. For security reasons I renamed all community strings in the file, I hope it is still readable for you.

Link to the dump was sent to you per pn.

Thanks for the help,

Greetings
Tom

dump

on server console to create core dump of server process and send it to us for analysis?

Best regards,

the server runs normal now after activating the dump...

But I think there is a problem now with the pollers or discovering. Discover is activated, but no new devices are found until now.

Here is the output:

Is this a normal behavior?

DiscoverInterval is set to 6000 and active.

If it is Windows, please add following lines to your netxmsd.conf

CreateCrashDumps = yes
DumpDirectory = C:\

This will cause server to create crash dumps in root of disk C:. You can set any other directory for dumps of course.
When it crashes again, please send dumps to dump@netxms.org.

Best regards,
Victor

I deleted round about 10 devices and changed the discover parameters. After restarting netxms core the server crashes after about 3 minutes.

Server restart, crash after some minutes.

server restart, disable discover - server restart - crash after a few minutes.

server restart, now it runs for about 10 minutes without problems.

Any idea? I think it happend because I deleted some devices...
