Developers of Sympa

[Thomas Berry <address@concealed>]

It's not causing any operational problems; the member count is used just 
for informational purposes.  We have a few web interfaces and command 
line tools that use the count to provide information about the mailing 
list being used.  I noticed this behavior occur with other lists, but 
since it wasn't a high priority issue, never tried to find out how it 
could be fixed.

As for this list, it is used 4-10 times per day. 

When nocache was used, an undef value was returned.  I have a script 
that isolates the sympa code that dumps the members of a list and it has 
always returned the full list of members even though the member count 
returns 0 (or undef with nocache).

We actively check for database outages and have seen no indication of 
database connectivity issues in the Sympa logs or other monitor sources 
(maintained outside the list server).
