Hi, Jeff!
There were some fixes relate to the memory statistics in revision #9322.
Anyway, the problem was that the statistics were not reported properly,
but the internal behavior was working as it should. Therefore, your
OpenSIPS did run out of memory. Try to update your sources and then let
us know if you still have these issues.
Best regards,

Hello,
On Opensips 1.7 build 9142 (July 6 this year), I have encountered an
interesting problem. First, we see errors like this:
WARNING:core:fm_malloc: Not enough free memory, will atempt defragmenation
ERROR:core:build_res_buf_from_sip_res: out of pkg mem
ERROR:tm:relay_reply: no mem for outbound reply buffer
WARNING:core:fm_malloc: Not enough free memory, will atempt defragmenation
ERROR:core:build_res_buf_from_sip_req: out of pkg memory ; needs 347
Various modules fail in various ways because of memory problems. The
statistics show something very interesting:
pkmem:0-total_size = 2097152
pkmem:0-used_size = 75796
pkmem:0-real_used_size = 99612
pkmem:0-max_used_size = 101384
pkmem:0-free_size = 1997540
pkmem:0-fragments = 6
pkmem:1-total_size = 2097152
pkmem:1-used_size = 102216
pkmem:1-real_used_size = 127448
pkmem:1-max_used_size = 130864
pkmem:1-free_size = 1969704
pkmem:1-fragments = 60
pkmem:2-total_size = 2097152
pkmem:2-used_size = 2053012
pkmem:2-real_used_size = 2147376
pkmem:2-max_used_size = 2154380
pkmem:2-free_size = *4294917072*
pkmem:2-fragments = 20
pkmem:3-total_size = 2097152
pkmem:3-used_size = 2093180
pkmem:3-real_used_size = 2189356
pkmem:3-max_used_size = 2193028
pkmem:3-free_size = *4294875092*
pkmem:3-fragments = 20
... and on through pkmem:8.
The free_size for processes 2 and 3 is approximately 4 GB, yet only 2
MB total per process. The values for the other processes are okay.
Does this look symptomatic of a problem that has already been fixed,
or do we need to do more investigation?
