Hi Alex,
Typical approach in this case is to do the accounting via a very fast
backend (like db_flatstore, into a text file) and import the files
off-sync into db (like every 5 mins).

Hi,
We are looking to deploy accounting/homer integration on Opensips
3.0.2.
As the first step deployed acc module with pgsql backend.
The config seem to be pretty straight-forward - see attached.
It appears that as soon as volume hits about 30-35k in_use
transactions - the server stops replying to new requests (or give
408 Timeout) and syslog gets filled with:
Apr 22 10:19:38 opensip1 opensips: Apr 22 10:19:38 [19258]

Although, the remote Postgres service is on SSD with relatively
small network latency, it appears to be the bottleneck.
The initial assumption was the Opensips acc uses no-blocking SQL
calls (since cdrs are not real-time).
Another observation:
opensips only opens 20 SQL connections to postgres via tcp 5432.
I have tried playing with db_max_async_connections, however to no
avail.
Any suggestions to troubleshoot ? or any alternatives for
accounting in high volume applications would be greatly appreciated.
Thank you.
