Hi,
I have run in to an issue when sending diameter requests using the ims_diameter_server
module. Shared memory keeps increasing and are not being freed until restart of kamailio.
This leads to all shared memory is being used and no more are able to be allocated.
This only happens when the request is sent synchronously. When sent asynchronously shared
memory is being freed as far as I can see.
have anyone ran into this issue and found a remedy or can give some pointers how to
proceed?
Following functions have been used for sending requests.
diameter_request([peer], appid, commandcode, message)
diameter_request_async([peer], appid, commandcode, message)
route[CHECK_LOCATION] {
diameter_request("hss.ims.test.local", "16777217", "306",
"[ " +

\"Flags\":64, \"int32\":10415 }, { \"avpCode\":258,
\"vendorId\":0, \"Flags\":64, \"int32\":16777217 } ] },

xlog("L_INFO", "Sent Diameter request");
}
