I also have a memory leak in my 3.14.7, vxworks (T2.2.1), which
occurs when I do large (~16 kB) CA transfers. Haven't looked
too hard, yet.

Hi all,

on some IOCs we see that the free memory becomes less and less.
Especially when we restart our channel archiver, the free memory in the
IOCs becomes much less.

My possible explanation for this is that channel access has not a free
memory block of the desired (big) size in its private pool, so that
additional memory from the system pool is allocated - and never free'd.
Is this possible? Can the channel access pool become fragmented? If YES:
Is there a solution for this in later versions? Or a patch?
We are using Epics 3.13.10 with vxWorks 5.3.1 on mvme162-532A (16 MB)
Thank you
Bernd
