NCPA repeating error in syslog?

Post by lveitch »

Hey everyone,

I didn't know where else to ask this but I am running the NCPA agent on a Ubuntu Server 24 that is sending syslog data to NagiosXI but I noticed all of this data in my syslog repeating and I have no clue what to make of it. Can anyone tell me what might be the issue?

Code: Select all

You might try doing a search of the internet for the first line.

Yeah, no problem.

We got it on our radar at least.

The fork error means a parent process is exiting before the process it ran. That's from a search result.
Look for a long running service and at your timeout settings.

Hi lveitch,

This seems to be a message that many NCPA users are seeing across multiple Linux distros lately. We are currently looking into the cause of this error being logged and hope to have a resolution for everyone soon.
Cheers,

I was just curious to see if this was addressed or not. I have not implemented any fix attempts or anything since noticing this issue a few months back and just wanted to ask if this got fixed

Hi @lveitch,

The syslog threading errors should be fixed in NCPA version 3.2.1 and up. The newest release 3.2.3 has had the syslog messages cleaned up even more.
Cheers,
