Hi, Thanks, How do i find memory leaks? when my application starts the it shows the following values:
shmem:fragments = 143898 shmem:freesize = 3446570952 shmem:max_used_size = 861854768 shmem:real_used_size = 848396344 shmem:total_size = 4294967296 shmem:used_size = 319676976
I divided the "real_used_size" with the "total_size" and notice that it is 20%. So, this is my initial value of the application.
After 2 months with 40,000 calls per day, the relations between these values is 39%. (doing a reload of the data that occupies 20% failed due to "no memory") So, 19% occupation of memory is normal for this amount of calls? or is it a memory leak? if it is a memeory leak, how do i see where?

avp's are associated with the transactions, so they free'd when the transaction stops(and calls are composed of transactions). This is true for dialog information as well (dlg_var's etc.). Continuous growth in memory at a constant call rate (incoming sip requests) might mean a leak. If you need statistics about the total memory usage you can use `kamctl fifo get_statistics all` and check for the shmem real_used_size and max_used_size fields.

Hello,
Too little information to go on here. A reload might fail mostly because data from the DB (e.g. with carrierroute case) is first loaded into private memory (the sql result). Depending of the module there are other tricks you could do (decrease the number of fetch rows the query returns etc.). The out of memory condition affects shared or private mem. Try to use at least 15 MB for PKG mem.
If the 39% is with traffic, then it's normal, if you don't have any traffic I still would not worry. The thing that worries me a little is the value, you are using from the start around 0.8 GB of used shared memory... this is a lot. From the percentages you provided it looks ok....
