Symptoms

There is some kind of memory leak on GG replicat for Postgres. (extract and pump works from Oracle DB)


After startup, all replicats work fine, but during next 7-10 days, memory usage/allocation by each replicat process growing infinitely.

About after 7 days, host memory limit is reached and server starting to use swap.


Tried to limit memory usage with CACHEMGR CACHESIZE 1G - it doesn't work.
