Re: hung process

In my experience this sort of problem often arises from users putting in damn fool enquiries (e.g. select * from largest_table) and, getting tired of waiting for a result, switching off the terminal. Once the terminal session is lost init becomes the parent, as it does for all orphan processes. Network problems could also cause this. Talk to your users - find out their problems - educate them (threats of violence should suffice ;-) Ian Oscar Goldes wrote: > > Hello, > I am using informix online 7.2 over SCO Unix. > I frequently notice that there are a lot of hung process. > Specifically, I saw that two process were eating up nearly 100 % cpu time (a pentium biprocessor) as seen with vmstat or cpusar. > Both of them had huge ammounts of cpu time as by ps. > The two processes turned out to be dbaccess sessions, which had 1 as parent process, but did not belong to root, just to normal users. > They could be seen from onstat also. > Killing them solved the cpu usage problem.
