[SR-Users] RPC Socket stops answering after a few time.

[David VILLAUME]

Hello,

After a new check , can’t get answer, on the node for :  “kamctl rpc dlg.stats_active”

And I see in logs that about for dmq replicated calls (dialog [dialog.c:2400]: rpc_dlg_stats_active(): not active - state: 5) , disappear after the previous message appears.

After trying a “kamctl rpc dlg.stats_active”, I cannot even have answer to ‘kamctl rpc core.uptime’ anymore.

Have you any idea to go ahead with troubleshooting ?

Regards,
David

Hello Daniel,

Thanks for your quick answer.

In fact I cannot even enter in kamcmd interactive mode after this happens.

Seems that “ kamctl rpc core.uptime “ can still do the job.

I’m using kamailio_exporter  with the following methods : tm.stats,sl.stats,core.shmmem,core.uptime,dispatcher.list,dlg.stats_active.

I haven’t process that requests longest data on the host, so I’m not sure if it can be related.

Regards,
David

Hello,

what is the command you run? Maybe the result is too big and you need to change the params for ctl module.

Or is it for all commands, including those printing small data, such case core.uptime?

You can also try the 'kamctl rpc COMMAND', which uses jsonrpcs, the error you pasted is from ctl module, used by kamcmd.

Cheers,
Daniel

Hello,

I’m having problem with RPC socket that stops answering after approximatively  one or two hours.

Version is 5.2.7

My principal host with exact same version and configuration has no problem, only the backup node (Keepalived + DMQ) encounters the problem.

I could catch this log about the problem, but didn’t find any reason for this :

Jun 18 10:53:33 sbc-kam-partner-b kamailio[83170]: ERROR: ctl [binrpc_run.c:600]: rpc_send(): ERROR: binrprc: rpc_send: send failed


My configuration about rpc :

loadmodule "jsonrpcs.so"
modparam("ctl", "binrpc", "unix:/var/run/kamailio/kamailio_ctl")
modparam("ctl", "binrpc_max_body_size", 1024)


Do you have any idea to troubleshoot this ?

Regards,
David
