I got an Oops message in kernel 2.4.20 this morning. The server is a brand
new Pentium III single processor Dell Blade 1655MC server, with 2GB of RAM
and SCSI hard drives. There are two 512 MB swap partitions allocated (one
per hard drive) and mounted.
The application (thorslave) apparently was trying to allocate memory, and
instead of getting some out_of_memory condition, the kernel triggered an
Oops.
The ksymoops results follow.
Can anybody provide some light to it? Is there any known bug in kernel
2.4.20 related to this Oops that got fixed in the 2.4.21pre versions?
Thank you,
Flavio Villanustre
