It's the first time I experience such an issue, but I can't seem to get SSL for IMAP or POP3 working. My OS is CentOS 5.7 x64, fresh Koloxo 6.1.10 install.

[root@srv ~]# tail -n10 /var/log/koloxo/courier
tcpserver: status: 1/40
tcpserver: pid 24153 from 127.0.0.1
tcpserver: ok 24153 srv.domain.com:127.0.0.1:993 :127.0.0.1::36930
/usr/bin/couriertls: error while loading shared libraries: libk5crypto.so.3: failed to map segment from shared object: Cannot allocate memory
tcpserver: end 24153 status 32512
tcpserver: status: 0/40[/code]
[code][root@srv ~]# cat /var/qmail/supervise/imap4-ssl/run | grep soft*
/usr/bin/softlimit -m 180000000 \
[root@srv ~]#

(I've already tried higher and lower limits here, also in the other run files like for pop3-ssl)

[root@srv ~]# cat /etc/courier/imapd | grep ULI*
##NAME: IMAP_ULIMITD:0
# IMAP_ULIMITD sets the maximum size of the data segment of the server
# process.  The value of IMAP_ULIMITD is simply passed to the "ulimit -d"
IMAP_ULIMITD=65636
[root@srv ~]#

(Also tried higher limits here, like 128M)

[root@srv ~]# rpm -qa | grep krb
krb5-libs-1.6.1-62.el5
krb5-devel-1.6.1-62.el5
krb5-libs-1.6.1-62.el5
krb5-devel-1.6.1-62.el5
[root@srv ~]#

(Of course I've also tried reinstalling the krb5-libs, in case there's something wrong with them)

[root@srv ~]# free -m

Nothing I've tried works and there's also no solution that works for me on Google. I've never experienced something like that before and I hope someone can help me, because this really starts to bother me.
