When loading RHEL 3 U9 on Dell PowerEdge 2970, system hangs at kudzu
Last modified: 2008-08-02 19:40:35 EDT
Description of problem: When I remove the link in /etc/rc3.d for kudzu, the machine boots up fine. I was able to run kudzu after boot up yesterday and it returned ok, but when I reenabled kudzu at boot it hangs. I then disabled kudzu during boot again and it boots, but when I run kudzu after boot up now, the kudzu process goes into an uninterruptible sleep state (D in ps aux output) indicating that it is blocking on I/O but there is no I/O activity. When the server is in this state, the load average continually climbs and you can not kill the kudzu process. The only method to get the machine back under control is to reboot the machine. I checked and the kernel is the 2.4.21-50. This server is the Dell PowerEdge with Opteron processors and 2.5" SAS drives. At this point I am stumped as to what to do next. Any suggestions? Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
Strace it to see where it's hanging. Being stuck in 'D' generally implies a kernel issue.
