Hello,
1. Yes, there is at least 2 times more space than core dump needs.
2. I could find nothing, unfortunately...
I can only see that problem is related to tm.so library:
kamailio kernel: [ 1051.432646] kamailio[2678]: segfault
at 12 ip 00007fa8b592ae43 sp 00007fff48ff9f40 error 4 in
tm.so[7fa8b5917000+72000]
BR,
Dmitri
I don't know it this applies to you but also check
the following:
1. You have enough space in the partition where $COREDIR is created
2. Check that the user that runs kamailio (usually openser) has read
write access on that directory
Also if you grep for core in the /var/log/ directory I believe that
there might be some lines either in dmesg or in messages that tell you
if a core was created or not.
Hope what I said is not redundant and it helps.
