Quintum A800 event log error.

I frequently get following error from Quintum A800 saying that:

1. failed to allocate DSP receive tone….

2. EXCP : 39895873:HttpD: E_RECV error (0x5023)
EXCP : 39895873:HttpD: Source addr=67.69.129.43

3. EXCP : 35511796:SharedMemIdThrot=0x460000
EXCP : 35511796:sminfobuf.count= 0x0; max=0xc; RetCode=0x0
EXCP : 35511796:sminfobuf.name= HLFT; flags=0x4; count=0x0
EXCP : 35511796:HttpD: Maximum connections exceeded (0x0)

I would really really appreciate if someone could shed some light on the above errors.
