Problem with skiplist

We are using cyrus-imapd 2.3.7. We had problems so we applied fixes 
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
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 we saw that someone
a linux

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

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

Thanks a lot!

Kind Regards,

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.
