[SR-Users] Keep Number of Messages per Source

[AliReza Khoshgoftar Monfared]

Hi Daniel,

I am setting the htable as follows:

modparam("htable", "htable",
> "message_counters=>size=10;autoexpire=10;initval=0;updateexpire=0;")


* autoexpire=10 to have items expire after 10 seconds (in this example)
* updateexpire=0 to force the expiration no matter the items were updated
or not

Yet, I can see the values persist.


Another concern is that, if I specify a number of child processes in my
config (e.g. children=4), then will it be safe to increment the hash table
entries in the route block upon receipt of messages? i.e will the table
entries that reside in the shared memory be precise? or do I need to
lock/unlock them while updating?


Thanks
Alireza
