Is that a fact :-) In my case it was:
EPRODUCTIONSYSTEMRUNNINGOLDLINUXDISTANDTOOLITTLETIMETOMAKEAGOODBUGREPORT
The system in question has now been upgraded to redhat-5.1!
Netscape-4.5 instantly segfaults on an NFS mounted homedirectory. Here is the decoded oops (the standard redhat-5.1 syslogd/klogd fails to autodecode the oops).(The oops was not in nfs_file_close).
[root@metallica oops]# cat oops3 | ksymoops /usr/src/linux/System.map Using `/usr/src/linux/System.map' to map addresses to symbols.
