No, but I changed the execution order around so that this one is rotated
before the call to rotate syslog (which does do a syslog restart). We will see
what happens next month ...

Nothing was logged after 1 Jul (I posted that info in the first post). The
logging just stopped without anything being indicated in any of the logs.

I am using standard RH 9 stuff. I guess I could put the above entry in with
/etc/logrotate.d/syslog ... That would probably resolve it.
