Sympa might have died because of a message it failed to process. If so, 
sympa.pl might die again.
If it happens, please restart sympa.pl in debug mode ( '-d' option) ; 
this way you'll get STDERR printed on the terminal.

The queue processing deals with messages priorities (defined on a per 
list basis). This is very time consuming because after each message has 
been processed, sympa.pl scans the spool again to find out about new files.

The process could be optimized if sympa.pl scans its spool once only. 
But currently you'd have to patch sympa.pl.
