[suse-security] OT: VM killing sec relevant daemons
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Dear list,
I know I am (slightly) off topc with this question, but for me it is
definitely security related.
Since a few days the server of one of my customers keeps telling me (in
/var/log/messages):
prime kernel: __alloc_pages: 0-order allocation failed (gfp=0x1d2/0)
prime kernel: VM: killing process sendmail
prime kernel: __alloc_pages: 0-order allocation failed (gfp=0x1d2/0)
prime kernel: VM: killing process spamassassin
several times in a row.
After that it starts killing services and daemons, starting (always) with
spamd and amavisd, followed by nfsserver and sendmail, with cups only a short
time behind.
Also the netfilter tables get flushed at some point, but without so much as a
hint to when.
Does anybody have a clue what this could possibly be?
BTW memtest showed absolutely nothing so far...
About the machine:
P4 2GHz with 256 MB Memory,
2 HDD RAID1 as /, 2 HDD RAID1 as data storage
Linux 9.0 Pro with only samba, nfsserver, sendmail, spamd, amavisd and sshd
running.
TIA
Wolfgang
