INFORMIX SERVER / 5725A3900 / B70 - IDS 11.70

Starting in 12.10.xC7 the server could encounter a memory leak
in the global memory pool.  You can see this via onstat -g mem
reporting a large global pool:

Pool Summary:
name         class addr     totalsize freesize #allocfrag
#freefrag

...
RA_req_2993  V     6a50c028 4096      1832     2          1
global       V     4722d028 2059264000 12649288 22922651
176122
89           V     49b00028 40960     912      64         3
...

You can see in the above output the global pool is ~2Gb in size.
If you then run

onstat -g afr global | awk '{print %5}' | sort | uniq -c   (and
then sort it again) you will see the following file name/line
number should dominate the memory allocations:

    165 rstrans.c:8867
    167 rstrans.c:8871
21879369 rstrans.c:8875
      1 sapimem.c:291
     49 session.c:238
    349 session.c:572
      2 socdevpoll.c:589

From the above the memory allocation at rstrans.c:8875 has over
21 million allocations.
