Hi everyone,

I am using sms service to send and receive sms  
sms send works fine but sms is not getting received using my application.

when I run my receive code i.e. le\_sms\_AddRxMessageHandler, then it gives some ‘memory pool overflow’ indication in logs  
**LE\_FILENAME le\_mem\_ForceAlloc() 841 | Memory pool ‘.le\_sms\_ClientData’ overflowed. Expanded to 1 blocks.**  
and application is not executing ‘messageHandler’ function code.  
as my all methods like sms\_getType, sms\_getTel, sms\_getText etc are called in this handler function, it is not getting executed and sms text could not be retrieved.

logs:

```
LE_FILENAME InitPool() 303 | Memory pool name 'framework.hashMap_refle_sms_ClientHandler' is truncated to 'framework.hashMap_refle_sms_Cli'

 LE_FILENAME msgMessage_CreatePool() 112 | Pool name truncated to 'msgs-d26b22be0fe85bc15a90af10f7' for protocol 'd26b22be0fe85bc15a90af10f7d8a763'.

```

kindly give solution to receive sms .

I haven’t tried implementing sms receive, but what I can tell you is that the memory pool overflow is not a problem. It’s just a log message that indicates that the memory pool has been expanded to meet the allocation requirements.
