_______________________________________________Hi Jeremy
I went berserk and set very high values
MAXMSG_CLIENT=4194304
MAXMSG_STATUS=4194304
MAXMSG_DATA=4194304
But the problem is not resolved

What have you got them set to now?
I would double them again and again if needed.
There is one slight gotcha here. We had a system where the figure was bytes instead of KB in spite of the comments in the file saying they were KB.
Regards
Jeremy

Thanx Jeremy
Increased the limit and restarted, but still getting the same line in the logs.

Hi Chris,
You may need to change some memory limits in xymonserver.cfg
MAXMSG_CLIENT
MAXMSG_STATUS
MAXMSG_DATA
If you have plenty of memory I would multiply them all by 8.
HTH
Jeremy

Good day
I please need guidance to configure xymon on Ubuntu 24.04
I installed xymon from the default apt repository.
It’s a VM running in Azure and installed using the repo that was setup for a Ubuntu vem on azure.
Also changed the repo to the default mirrors.kernel.org and installed xymon from there.
# apt-cache policy xymon
xymon:
Installed: 4.3.30-2build3
Candidate: 4.3.30-2build3
Version table:
*** 4.3.30-2build3 500
500 https://mirrors.kernel.org/ubuntu noble/universe amd64 Packages
100 /var/lib/dpkg/status
Xymon does start and generates the pages which I can view but is missing the client tests (disk, cpu, memory etc..), and the rrd graphs
Confirm port 1984 is listening
I see a bug was also recently reported here https://bugs.launchpad.net/ubuntu/+source/xymon/+bug/2078638
I see similar entries in the xymon {clientdata.log, rrd-status.log alert.log } files, repeating.

This is a fresh install and the only change I made in xymonserver.cfg are:
XYMONSERVERIP=”server ip”
Firewall disabled
Apparmor disabled
Thank you.
