I am testing Xymon 4.3.7 and I am trying to monitor about 3000 host pcs. If I get over 2000 hosts, then xymonnet continually crashes. OS is Opensuse 12.1.
I am simply trying to monitor the systems for connectivity right now, using fping.
Is there a limit on the number of hosts that Xymon can monitor?
Are there any other options that I can look at to see what is causing the error?
Does xymonnet give a core dump, or any log messages? Does xymonnet crash when starting to probe, or part-way through?

Sorry for the delay in responding to this:
There does not appear to be any core file or log messagess that indicated why it crashes,
However, most of the hosts that I am pinging are DHCP and I am seeing a lot of issues where is it unable to resolve hostname.

I make backups of the hosts.cfg file before adding hosts, so when it crashes, I just restore the last working hosts.cfg file. I am trying to add hosts in smaller increments to determine just at what point the the program crashes again.

They should appear in the ~xymon/data/tmp/ directory

Definitely some issue with DNS lookups. I would be interested to hear if the soon-to-be-released 4.3.8 version works better for you ? You can download it from http://xymon.svn.sourceforge.net/viewvc/xymon/branches/4.3.8/?view=tar

No.

Anything in the xymonnet logfile ?
