Yes, but still haven't tried Reiser! By all means stay away from zfs (solaris). 
Despite all the hype, it is much slower than plain ufs.

Still spool is much more efficient than file. Imagine that file store has to 
lock the sms-list while it is writing the store-file from scratch. And with 
long Qs this could take some time.

Nikos

  Yes, I've benchmarked ext3, ext2 and xfs and ext2 is by far the best 
performing filesystem for spool store.


  At least on my experience, ext3 gets very sluggish on stores over 50K. 
Regarding xfs, despite being quite faster than ext3 in loading the store, 
increased the load on my system under heavy traffic.


  IMHO, ext2 is the way to go. However, if you're sustaining heavy traffic the 
spool store stresses the filesystem a lot so I'd recommend you to use a 
dedicated ext2 partition for the store: you'd still use the more reliable ext3 
for the OS while getting the speed of ext2 where's needed. Furthermore, if the 
ext2 partition crashes you'd be able to unmount it and repair it without 
rebooting the box.

    Hi Nikos,
    I can't use spool store-type right now since kannel runs on ext3 
filesystem. I remember reading that there were performance issues if you have a 
large queue+spool+ext3. If I have no other choice, I can partition the system 
and create an ext2 or xfs partition just for the queue. However I want to do 
that as a last resource solution(and hope that the problem really doesn't 
happen again).
    On the other hand, there are a couple of good free smpp smsc simulators. 
SMPPSim(free and open source) or Logica's simulator for example.

      Hi,

      I cannot find anything wrong with the code at that point. However, it 
looks like memory corruption. Could you please use spool instead of file? It is 
safer, more efficient and faster than file. In addition it uses different 
memory structures than file and you should get away with it.

      I will update and run valgrind on it over the weekend. Unfortunately, I 
don't have smsc connections, but I hope I can catch the problem with fake smsc. 
If not, someone else from the list will have to look at it.

      BR,

        Hi,

        How can you say they are the same? Even the the problem is different 
this time.

        Anyway I 'll have to look at it.

          Hi Nikos,
          Thanks for answering. First of all, i'm using the file store-type 
option and there is plenty of free disk space.  
          I'm using the latest CVS(cvs-20090902). Here are the logs+addr2line

            Hi,


            No, this is the right place for debugger info.

            First make sure that your partition is not getting full and kannel 
has space to write the Q.
            Seems you are using spool type for Q storage and it runs out of 
unique hash strings. But I cannot be sure, since your addr2line output is from 
an older CVS and reports wrong line numbers.

            Please update to latest CVS and repost.

            BR,
            Nikos

                Hi, 
                We are using the latest CVS and have found this PANIC bugs. 
This has happened to us 3 times in around two weeks. We are not able to 
reproduce them....the only thing we know is that it seems to happen when the 
store size is very large(100,000+ messages). We are using the "file" store 
type. Below are the bug reports:


                The first one is:

                Also, for some strange reason, after the PANIC bearerbox

                Could anybody please hint me in how to solve this issues?
