| |
Hello !
I am running the 2.4.20 kernel on a system with 3.5 GB RAM and dual CPU. I am running bonnie accross four drives in parallel:
bonnie -s 1000 -d /<dir-name>
bdflush settings on this system:
[root@dyn-10-123-130-235 vm]# cat bdflush 2 50 32 100 50 300 1 0 0
All the bonnie process and any other process (like df, ps -ef etc.) are hung in __lock_page. Breaking into kdb, I observe the following for one such bonnie process:
schedule(..) __lock_page(..) lock_page(..) do_generic_file_read(..) generic_file_read(..)
After this, the processes never exit the hang. At times, a couple of bonnie processes complete but the hang still occurs with the remaining processes and with the other processes.
I tried out the 2.5.33 kernel (one of the 2.5 series) and observed that the hang does not occur. If I run, two bonnie processes, they never get stuck. Actually, if I run 4 parallel mke2fs, they too get stuck.
Any clues where this could be happening?
Thanks -Manish
