Siemens M20 drops Message IDS ???

Has anyone else seen this behaviour with a M20 (firmware v5.4) ?

...some time later...

The message identifier of 233 is lost - I guess due to the CMS ERROR 500 reported
in response the first attempt to send the SM. But, I've asked for delivery reports
and some time later I get;

2002-09-06 10:32:57 [9] DEBUG: AT2[WWW]: <-- OK
2002-09-06 10:36:50 [9] DEBUG: AT2[WWW]: <-- +CDS: 24

2002-09-06 10:36:50 [9] DEBUG: AT2[WWW]: Numeric receiver  <0868210725>

I don't get a report for 234 - next one in is for 235. This really messes up the report
handling as you might imagine. I get a lot of CMS ERROR 500's for some reason.
Anyone else seen this ?
