Just an observation that I have not heard of yet. I have a filesystem product that until recently relied on some TTW Script(Python)s to do interfacing with some ZSQL Methods. What happened in that configuration was refcounts of those python scripts and their associated containers (in cache extreme detail) incrementing and never going away, a substantial memory leak that necessitated restarting the server regularly. They showed up on the main Debug page in the Top Refcounts listbox as lots of Acquisition.ImplicitAcquirerWrapper-s. So, just to see if it was the Script(Python)s or the code itself, I put identically the same code as methods in the filesystem product. Result: No more runaway memory usage. :) YMMV. -- Jim Washington
