slow store_load with large queue

Hi.

I've copied both devel and users list to get quicker response, sorry if
it's not right.

We are suffering from quite slow store load (about 100sms/sec) with large
queue (about 100k MTs).

What could be a possible reason? Could it be slow disk or is there a bug
itself inside the kannel?


Also we encountered another error while restarting bearerbox:

NOTE: we are using simple scheme bearerbox <-> sqlbox and when we are
restarting we are closing sqlbox prior to bearerbox
