Hello,
We use 7.4.6 version and now we have a bad performance on our
production server. We detected several strange messages in a log file :
LOG: statistics buffer is full
LOG: statistics buffer is full
LOG: statistics buffer is full
When i search on mailings list archive, i found a patch to increase the
buffer size in src/include/pgstat.h
-#define PGSTAT_RECVBUFFERSZ ((int) (1024 * sizeof(PgStat_Msg)))
+#define PGSTAT_RECVBUFFERSZ ((int) (16384 * sizeof(PgStat_Msg)))
And when i look the same file on the subversion trunk, the
"PGSTAT_RECVBUFFERSZ" constant is defined in a new file :
src/backend/postmaster/pgstat.c but with a same value.
Can you explain this statistics buffer problem ? And increase this
buffer size is a good resolution ?
Thanks for your help
Best Regards,
Jérôme BENOIS.
