Multiple -HUP to syslogd should not be delivered.

Currently /etc/logrotate.d/syslog 
delivers a -HUP for every file.

This is incorrect. It should use sharedscripts command
for example like one from /etc/logrotate.d/samba

Also see

for a similar report with apache log rotation

 Very good it was fixed.
 Without this fix a race often caused sysklogd killed
 (when second -HUP gets delivered during first -HUP processing)
 This often happened with slow computers.

 To model such problem just do

 while true ; do killall -HUP sysklogd ;  done

 the sysklogd will get killed.
 Same thing did multiple -HUP from log rotation.
 Hopefully it will be fixed from now on in sysklogd.

 Also, check the other daemons for this type of problem.
 It is very annoying - server just dies one every one or two months.
 I found few (apache, exim, syslog)
 which now seems fixed. Check the other daemons to make sure 
 no multiple -HUP used for daemon restarting.
