Does "dmesg" show anything odd?

Not realy. Its quiet, only this strange messages comes in this 2 days also
in, thay allways look like that:

lmtpd[3467] general protection ip:7f2e45ffdb2e sp:7fff4ee81968 error:0 in
libdb-4.6.so[7f2e45f2d000+136000]>> I didnt changed anything lately, but
yesterday my cyrus starts rise cpu

But it still work already for 4 hours here, even if this message is once in
my dmesg now.


If you attach to a hung process with "strace -p {pid}" what does it look
like?

Now its run, and as its produktion server, i will leave it running as long
it will self :)
But next time and i am mostly sure it will come again, i will do that
strace.

I am running this mailbox already since 2003. Cyrus had some nasty problems
with berkleydb few times in the past (2.2.x versions). But for last 2 years
i never had realy a problem with it.

Did you restart the services after the update?
I am on gentoo box.

Gentoo is ok, i am self in trouble because i run unstable ~x86_64 keyword.
I know that, so i have to manage my problems self. Gentoo has nothing to do
with that.
But you've right, something with system is not right at the moment.


If cyrus goes in to the blocking state,

Sounds to be like Cyrus is not the only thing getting hung,  which
indicates the problem probably lies elsewhere.

Actualy only cyrus processes are in trouble. iprune do it job, as example,
but never get out to promt.

I got my kernel now updated to 2.6.27.9. It runs now 2.6.29.7. If it crash
again, i reboot to new kernel and will see if something is changed.
