NetXMS Forum

Yes I know.
I have now 4 GB RAM and 4GB swap and real used virtual memory is about 60%.

But after some time (about after 24 hours) stops reading from SNMP. After restarting nexmsd , DCI collecting data normally.

Ubuntu 14.04.3 LTS (GNU/Linux 3.16.0-30-generic x86_64)
NetXMS 2.0-RC2

I have problem with increasing memory consumption.
After restart server all is in normal state.
Server has 3GB RAM.
Have you somebody the same experience?

No, we using only all with 2c SNMP.
I had to reconfigure NetXMS with only one zone without netxms proxy.
I try if is will be the same problem in this configuration.
Now debug running  2 hours without crashing.

This fault is only when is set  in nxagetd.conf on Proxy client for NetXMS.

EnableSNMPTrapProxy = yes

Hello.
My environment is NetXMS 2.0-RC2 Ubuntu server 14.04 LTS.
I have the problem that netxmsd crashes after some time.
In syslog is:
 NetXMS kernel: [248886.914205] netxmsd[24807]: segfault at 18 ip 00007fa108d8d4d5 sp 00007fa0e88b7660 error 4 in libnxcore.so.2.0.0[7fa108c84000+1c9000]

I tried, export database and reinstall NetXMS. But it is still same.
I using zones and proxy for SNMP, NetXMS agent and ping.
