Hello,
I have a mailing list here running for one of our customers
which is getting extremely large and therefore slow.
The list is a newsletter list with one post a week - that doesn't
harm me. But I hav about 500 new subscribes a day which makes up to now
about 150000 members - and thats my problem:
the config.db is
-rw-rw---- 1 www-data www-data 15587680 Apr 18 14:13 config.db
and therefore is blowing my main memory. Lokk at this output of "top"
31084 www-data 18 0 81M R 48.7 10.8 0:07
/usr/bin/python -S /usr/lib/mailman-aldi/scripts/driver subscribe

/usr/bin/python -S /usr/lib/mailman-aldi/scripts/driver subscribe
so every subscribe is between 40 an 80 M in core. At the moment the
system is running an own apache
for this with a connect limit of 15 which gives 768M main memory used
plus 200M swap. When I remove
the apache limit, the system goes into swapping - more subscribe
requests arrive - less memory
an about 5 minutes later - BANG
Any Idea?
Any hint?
Regards
Juergen
