Hello everybody, Since 7 month I use hobbit to observe the availability of our VSE, VM and Linux systems running on IBM z9. The hobbit-server 4.2.0 is running in sles10 sp2 on this IBM z9. Everything worked well until last friday. In the Current Staus screen the icons for bbd, bbtest, http and the complete conn column changed from green to purple (no report). After a system reboot everything seems to be ok again because all icons were green. But after some time the problem was back, the icons for bbd, bbtest, http and the complete conn column changed from green to purple (no report). When I log on to hobbit and run 'bbtest-net' manually all purple icons change to green except the bbtest icon (still purple). After a while the already mentioned icon will change to purple again.

So it looks to me that bbtest-net will not restart after the interval of 5 min.

I have reduced the number of observed hosts from 20 to 10 and inserted --concurrency=N in the hobbitlaunch.cfg. But the problem still exists.

Here is a part of my hobbitlaunch.cfg

"bbnet" runs the bbtest-net tool to perform the network based tests -

i.e. http, smtp, ssh, dns and

all of the various network protocols we need to test.

[bbnet] ENVFILE /usr/lib/hobbit/server/etc/hobbitserver.cfg NEEDS hobbitd CMD bbtest-net --report --ping --checkresponse --concurrency=N LOGFILE $BBSERVERLOGS/bb-network.log INTERVAL 5m

These are my running hobbit processes

I cannot see any errormessage. There is enough space in the filesystem. Is it necessary to create a crontab entry to start bbtest-net every 5 min?

My colleagues promissed me, that they have nothing changed. I have no idea what happended. Every hint is appreciated.

kind regards Horst Rempel
