[Serusers] SER / Missing call records

[Darren Sessions]

All,

 

We're experiencing a problem with missing call records. There is nothing
in the log files that indicate a problem either with SER or our database
server and likewise there is nothing in the database server's logs to
indicate a problem. System loads are within reason on both servers,
network connectivity has been tested and verified, and a through
hardware shakedown on both boxes has been completed without any errors.

 

We first noticed this problem when our underlying vendor's bill (based
on minutes of course) did not correspond with our own. Upon doing a CDR
comparison (based on what was in both the acc and calls tables), we were
able to verify that the calls in dispute were indeed ours (based on the
sip call-id's IP addresses).

 

We're processing roughly 1.4 million calls per day on this SER server in
question. Out of those calls, 508 calls (give or take a couple hundred)
with a total duration of over 5,300 minutes - can not be accounted for
in any of the SER database tables.

 

We're running 0.9.5-pre1 with Suse Enterprise Server 9.0 (2.6.11
Kernel). Server is an HP DL380 with dual 3.2GHz processors with 6GB
physical ram (only 1.4GB in use system wide); disk space is not an issue
as well (only 10% in use). 

 

We've scoured the mailing lists and change logs for any hint of an issue
similar to ours without any results. The closest we've been able to come
that's anywhere near along the lines of our issue in any way that made
any sense were these posts:

http://lists.iptel.org/pipermail/serusers/2005-February/015102.html

 

At this point, we're not sure if this issue has something to do with the
FIFO and SER making bulk dump uploads with call data to the database, or
some other issue along those lines - or if this is a new issue all
together.

 

Any help would be greatly appreciated.

 

Thanks,

 

- Darren
