External Email - Use Caution Hello Ken, The output from your linux shell limits in the log show the following, cputime unlimitedfilesize unlimiteddatasize unlimitedstacksize 8192 kbytescoredumpsize 0 kbytesmemoryuse unlimitedvmemoryuse unlimiteddescriptors 1024 memorylocked 64 kbytesmaxproc 7823 maxlocks unlimitedmaxsignal 7823 maxmessage 819200 maxnice 0 maxrtprio 0 maxrttime unlimited I would set at least coredumpsize to something non-zero so you can at least get a core file saved that could be looked at. By default the limits on my Ubuntu 22 system are: $ ulimit -areal-time non-blocking time (microseconds, -R) unlimitedcore file size (blocks, -c) unlimiteddata seg size (kbytes, -d) unlimitedscheduling priority (-e) 0file size (blocks, -f) unlimitedpending signals (-i) 378881max locked memory (kbytes, -l) 64max memory size (kbytes, -m) unlimitedopen files (-n) 1048576pipe size (512 bytes, -p) 8POSIX message queues (bytes, -q) 819200real-time priority (-r) 0stack size (kbytes, -s) 8192cpu time (seconds, -t) unlimitedmax user processes (-u) unlimitedvirtual memory (kbytes, -v) unlimitedfile locks (-x) unlimited You can try setting the core file size to unlimited with, $ ulimit -c unlimited... then check the value was changed to something > 0 ...$ ulimit -a You could increase memory size (and as many shell limits as possible) to unlimited to get the max size allowed by the system in the script you use to run recon-all, and then try running recon-all again to see if you can retrieve a core dump file. - R.
