[OpenSIPS-Users] db_postgres: no private memory left

[Anca Vamanu]

Hi again,

I missed the part where you said you increased the private memory to 
100M :) .
The dr_reload command fetches one chunk at a time - you can modify the 
number of rows fetched by setting fetch_rows parameter in dr_module .But 
there could also be a leak if you say that this happens after a couple 
of reloads.
I suggest you to do a monitoring of the private memory for the FIFO 
process. You can use the following command:

/opensipsctl fifo get_statistics pkmem: | grep pkmem:1-/

and run this with a script and collect the data.
You can also use OpenSIPS-CP to monitor the pkgmem_real_used statistic.

Regards,
