Can not take any more calls after certain number of calls

Hi All,

 To check the performance of my HMP application I have tested it with a tool to repetedly scan the channels sending INVITE Packets. After scanning so amny times I have found that it HMS is not able to answer any more new calls though the channels are released properly and in state to take calls. From RTF logs I have found followings:

01/28/2009 16:59:34.479    936        5016 sip_stack               Error        WARN   - TRANSPORT    - TransportUdpEventCallback - sock 11404: Receive failure, due to insuffficient buffer
01/28/2009 16:59:34.775    936        5016 sip_stack               Error        ERROR  - CALL         - CallLegMgrCreateCallLeg - already allocate 127 call-legs. maximum calls configuration 127.
01/28/2009 16:59:34.775    936        5016 sip_stack               Error        ERROR  - CALL         - CreateAndInitNewCallLeg - Failed to create new call-leg for transc 0x06D97188 (rv=-2)

Can anyone kindly suggest me what needs to be done to get rid of this error??

Is it any configuration problem in HMP?

Kindly Help.

RTF logs are in Attachment.

Thanks
