Problem with skiplist

[DEMBKOWSKI, Henryk (Henryk)]

Thomas,

We are using cyrus-imapd 2.3.7. We had problems so we applied fixes 
from http://permalink.gmane.org/gmane.mail.imap.cyrus/28033
which are now in 2.3.11 and higher. Do you know if there are additional 
changes in skiplist code in 2.3.11 beside above fixes? BTW, we are
planning 
to use new version 2.3.12 or 2.3.13..

We are using Linux and 

uname -a
Linux ms01 2.6.5-7.276.PTF.205323.0-bigsmp #1 SMP Mon Jul 24 10:45:31
UTC 2006 i686

At http://www.intevation.de/roundup/kolab/issue840 we saw that someone
recomended
a linux 2.6.19.2  http://www.intevation.de/roundup/kolab/msg12474

	My hypothesis is that using a linux 2.6.19.2 or later 
	_with_ skiplist should also develop no problems.

Do you think that we have to move to higher linux? And even we have
fixes
for skiplist we will still get errors due to linux?


Thanks a lot!

Kind Regards,
Henryk

Hello Henryk,

which version of cyrus-imapd are you using?

Which operation system are you using?
If it's Linux, what kernel version do you use?

In the past there was a bug in the kernel (mmap) that could cause
skiplist corruption.
