sam extension memory consumption

Hi! Sorry for my last mail being empty. I've compiled the current stable version of the pecl sam extension with xms support on windows XP, php 5.3 using VC6. I've got a rather simple php-script that just connects to a local Websphere MQ 6 queue and peeks messages. Each peek allocates memory, which does not seem to be freed afterwards. So doing this in a loop results in a php memory allocation error. I don't know, if this is the right place to ask for help with this issue. If so, any help is much appreciated and I will provide as much details as I can. If not, I'd be glad to be pointed to the right place. Thanks a lot, greetings, Nicolai Scheer
