Good Morning,
We are currently testing raw data reconstruction with AliEn through memcheck
and dhat. There is one suspicious report (see below for memcheck and the
others at the end of message). Please advise.
XrdSecProtocolssl:1480: XrdSecProtocolssl::CryptoMutexPool[i] = new
XrdSysMutex();
There is a new but no delete?

Thank you.

This was reported by dhat: so a single allocation of 1MB, little reads and no
deaths:
max-live: 1,048,576 in 1 blocks
tot-alloc: 1,048,576 in 1 blocks (avg size 1048576.00)
deaths: none (none of these blocks were freed)
acc-ratios: 0.00 rd, 0.25 wr (2,382 b-read, 264,522 b-written)

XrdClientVector.hh:64 rawdata = static_cast<char *>(malloc(mincap *

XrdClientVector.hh:158: if (rawdata) free(rawdata);
So this is fine?

delete is there in the destructor. So this is an odd one:
