Question on paxtests causing segfaults

Hi Scott,

I know official F11 comes in December.

The only issue besides the gui is I keep seeing these segfaults in my ossec hourly emails:

Oct 26 10:01:01 server kernel: anonmap[2257]: segfault at b77af000 ip b77af000 sp bf930bdc error 15
Oct 26 10:01:01 server kernel: execheap[2278]: segfault at 8927098 ip 08927098 sp bfe7eb8c error 15
Oct 26 10:01:01 server kernel: execstack[2285]: segfault at bf9f1570 ip bf9f1570 sp bf9f156c error 15
Oct 26 10:01:02 server kernel: shlibbss[2635]: segfault at 8aa5a0 ip 008aa5a0 sp bfa10dbc error 15 in shlibtest2.so[8a9000+2000]
Oct 26 10:01:02 server kernel: shlibdata[2642]: segfault at 523580 ip 00523580 sp bffa1bcc error 15 in shlibtest2.so[523000+2000]

Its happening hourly so I know its triggered in the crontab hourly asl

If I run them as root from the shell they execute properly.

Any idea's why segfaulting?

Thanks!

That is part of the kernel vulnerability scanner, its expected behaviour so nothing to worry about.

Hi Scott.

Okay thanks! Just worried when I saw segfaults.

Also wanted to report that the new plesk 9.2.3 with fedora 11 + asl 2.2 runs sweet!

Cheers!

Thats not coming from ASL, thats a real segfault happening with the statistics package. Are your plesk stats coming up OK?

I am looking at the stats of the traffic on the server and it shows 0.00 for 87 domains hosted on the server from a total of 94 domains only 7 shows some info but its minimal compared to past months.

What can be causing this?

Seems to happen in general with some Plesk installs:

In addition to the segfaults listed by the OP, I also seeing segfaults on execbss and execdata (grouped with the same ones listed by the OP). I am not running the ASL kernel. Is this normal?

Thanks
