0.64 is not that fine for production...
Memory leak occur cause libgcrypt (used by GnuTLS) do not free some
resource on exit. This mean that if your program keep loading and
unloading FreeTDS (and so you load GnuTLS that loads libgcrypt) you have
a leak. If your Perl application is a cgi-bin (executable) when unloaded
it free all resources however if you use Perl inside Apache using the
same process you can have the leak. However if you configura Apache to
limit request handled by sub-process you can remove the leak. Unlikely
it seems that GnuTLS do not include still my patch to support some
(weak) ciphers required by mssql so you have to patch it manually...
