Hi, I have a user running v1.9.0 with quite high numbers of concurrent calls (peaking at over 1500) and high call rate attempts (averaging about 100 per second for long periods). The amount of traffic is gradually increasing and, as it does, we are starting to see problems with "not enough shared memory".
We just started using Nagios to graph some of the metrics. Shared memory usage is well behaved most of the time, but it seems almost as if there is some threshold and when the call rate goes above this threshold, the used shared memory rapidly increases. One simple solution might be to add more memory. If we increased from 8GB to 16GB, would OpenSIPS be able to use a large part of this? Is there a limit for shared memory allocated when the program starts? Would there be a major benefit in upgrading the opensips software to, say, v2.3? Would you expect to be hitting problems with shared memory at these traffic loadings or might there perhaps be something on this server that makes it more susceptible? For example, it is using topology hiding. It also has background jobs running that send a lot of queries to the management interface. Thanks.
