Run an rpm verify on your ssh daemon... You may also want to get a tool like chkrootkit installed and running. rpm -vV openssh | grep 'S\.5' should work for SuSE. Post the output.

Upgraded a mail server to Fedora 9 with kernel 2.6.25.11-97.fc9.i686 #1 SMP Segfaults started about ten hours after the upgrade, early in the morning. There were nearly 400 in total, over four hours, affecting common processes: mostly dovecot-auth and spamd, but a few imap-logins. Then there was a gap of 13 hours with no segfaults, followed by segfaults in a Networker backup process and postgrey (that was bad) in the evening. The following morning (six hours later), there were segfaults in mostly postfix processes: smtpd, local, trivial-rewrite, qmgr, etc. Aug 11 02:27:39 mail kernel: dovecot-auth[16512]: segfault at a01d4c ip 00126c4a sp bf87ade0 error 4 in ld-2.8.so[110000+1c000] Aug 11 02:27:44 mail kernel: dovecot-auth[16521]: segfault at a01d4c ip 00126c4a sp bf87ade0 error 4 in ld-2.8.so[110000+1c000] . .
