[OpenSIPS-Devel] Memory Lick problem

[Liviu Chircu]

Hello Mike,

MySQL data looks like peanuts. We can safely ignore it. The following 
stats are quite interesting:

shmem:used_size = 3401120
shmem:max_used_size = 226816344

 From the *tm* module's point of view, this means that your server was 
hit, at some point in time, by a traffic of over 750 transactions/sec! 
If we add the memory consumption of other modules (dialog, usrloc), and 
a more aggressive peak hour, it may be quite normal for memory 
consumption to reach 1GB!

Can you share some details about the nature of your traffic? Do you 
expect traffic of over 750 cps regularly? If yes, then:

* -m 7192 is a good idea. You can probably reduce it a bit, like 4096.
* _-M 512 is too much_. 64MB should be more than enough for an OpenSIPS 
listener on *any* scenario.

If you don't expect such traffic, then it looks like a denial of service 
attack, case in which you should look into the *ratelimit* module.

Best regards,
