RE: {bb} bbd taking 99.9% CPU

["Jasper Filon" <jasper.filon@ritstele.com>]

Hey,

It seems like there is some scripts thats end up in some kind of a loop.. Do you see any errors in BBOUT? You said the problem only occurs in the weekends, is there maybe a script that tries to connect to a pc that is shutdowned during the weekends? 

Regards, Jasper

Hi,

I am maintaining BB-19c server on Linux RH 9.0. There are almost 150 clients (linux or Windows2000) with same version of BB client. The other external scripts are fping, IPGW, bb-mrtg ( bb-mrtg maintain 5 router's graph), top etc... 


>From the starting (2 months) I have been observing that the server become hanged-up on every weekends and other days it works fine. This hanged-up condition comes when the cpu utilization is high. I have captured top output from the server for the different weekends when it is about to hanged.

Please let me know, why this bbd is taking max CPU utilisation or has anybody else face this kind of problem.

Thanks
