Hello,
I have Xymon 4.3.7 running as server on a CentOS 6 box - no problems. I have a mixture of RHEL3, 4, 5 and 6, and CentOS 5 & 6 clients. These all work fine except for the RHEL3 client. That one shows purple for the cpu, disk, files, memory and procs tests. The tests seem to have picked up some data from the first run after starting up, but since then they seem to have reported nothing (and hence purple).
I have been looking into this for a while now, and am at a bit of a loss as to why just this one client is having a problem. I have stopped the firewall on both client and server, but that makes no difference. A tcpdump shows that data is being sent to/from the client/server.
Actually that is not quite true. Packets are sent to/from the client and server. However, the data relates to other tests - ntp, smtp etc, and not the cpu, memory etc tests.
In reply to others:
/tmp is not full, plenty of space available.
Although an earlier Hobbit version may work on RHEL3, I think that is avoiding the problem. (a) this is Xymon, not Hobbit, and (b) if this problem is hiding some other fault that may/may not be affecting other O/Ses then I would rather sort out the problem before it really does start to affect our other RHEL/CentOS clients. But thanks for the suggestion anyway. Yes, RHEL3 does use a 2.4 kernel.
John.
