[Freeswitch-users] high pdd

[Andre]

Going with the idea it’s IO related I did a db_cache status. I just disabled limit in my code by removing it but limit should be HASH not a database however I stills how a database.

 

Below is the results of the db cache status. I’m not real sure what its saying. I should have all registration and limit disabled and should not be using any sql database from my understanding.

 

Anyone know what the results mean? I’ve only tested 2 calls on this status.

Oh the log mod are commented off however I type console log level debug. Only errors that up are after the high pdd that say can't create more sessions or can't create more events for the pop code for the cdrs.
I have the config set to 30,000 sessions for testing but the problem happens about 3000 sessions and only 300 connected.

Thanks

Hmm, I have the cdrs going to a rabbit mq on the same box but I did try disabling the cdrs totally and got the same results.

For the SQL db I'd like to turn them off. The only one I need I the limit db however the Sofia reg internal still gets created. But it is in a Ram drive if that helps.

The switch is just bypass media and I write my own IP auth so no need to register.

Is there a way I can disable all dbs to see if that is the problem? I use no SQL now.

Thanks so much for your advice.

What about logging levels (debug?) and CDRs? Are they going to disk that might be causing high I/O?

 

Also consider trying something more powerful than SQLite for the database to see if that helps - eg PostgreSQL/MySQL

I run it now with no sql and the sqllite db in a ram drive. Should I run the entire process in ram drive? I’ve done that in the past but I can try again.

depends what its doing, but i suspect you are hitting some I/O wait of some sort.

What would cause very high pdd 12 seconds + after 3000 ports.  Wireshark shows reinvites.

 

I have tried many profiles and even many console apps both seem to have the same results after 2500 to 3000 ports (only 300 are connected)

The server cpu and memory are ½ the server limits.

 

Any ideas where to look would be great.
