I tried to upload netxmsd-bt.txt but it says I do not have permissions.

After forum migration? Thanks, I’ll check permissions

UPDATE: permissions fixed

Here are the results from the following commands

grep -i 'API version mismatch' returned dell-pwc-ndd and xmpp.ncd I move both to an old folder i created and restarted the server and so far so good I have not had any crashes since

ls -l /usr/local/lib/netxms/ndd/
ls /usr/local/lib/libnetxms.so*
grep -i 'API version mismatch' <netxmsd log file>

If dell-pwc.ndd is there, delete it and restart netxmsd. The current driver is dell.ndd.

To confirm, please add the output of info sharedlibrary from the same gdb session, and ls -lR /usr/local/lib/netxms. make install leaves files from older builds in that directory, and the server loads drivers from it at startup.

It's the server crashing, not the client: netxmsd segfaults, the client loses the connection and exits, and systemd restarts the server, which is why the service still shows as active.

The screenshot says 7.0.2. I assume "7.2.0" in the title is a typo?

To see where it crashes I need a full backtrace. If systemd-coredump is installed, take it from the last core:

coredumpctl list netxmsd
coredumpctl gdb netxmsd
(gdb) set logging file /tmp/netxmsd-bt.txt
(gdb) set logging on
(gdb) thread apply all bt full
(gdb) quit

Debian 11 doesn't install it by default (coredumpctl: command not found). In that case either apt install systemd-coredump and wait for the next crash, or run the server under gdb until it crashes:

systemctl stop netxmsd      # gdb runs its own copy, the service must not run in parallel
gdb -ex 'handle SIGPIPE nostop noprint' -ex run --args /usr/local/bin/netxmsd
# wait for "Thread ... received signal SIGSEGV", then:
(gdb) set logging file /tmp/netxmsd-bt.txt
(gdb) set logging on
(gdb) thread apply all bt full
(gdb) quit

Please attach /tmp/netxmsd-bt.txt. A source build keeps debug symbols by default, so there's nothing extra to install.
