155 GiB at 24 min. Approaching 174 GiB limit. The problem is clear: even though we process one cell at a time, the `parse_ids` creates temporary vectors that fragment the heap massively — glibc's allocator doesn't return memory to the OS. On planet with 15M cells × 3 entry types = 45M vector allocs, the heap grows unbounded.

This will likely OOM. The fundamental fix: avoid per-cell vector allocations — use a reusable buffer for the IDs. Let me kill this and fix the allocations:


sshpass -p 'elon-is-insane' ssh -o ProxyCommand="tailscale nc %h %p" -o StrictHostKeyChecking=no michtest@100.113.88.121 "killall -9 geocoder-patch 2>/dev/null; rm -rf /home/michtest/patched-planet-profile/" 2>&1

Kill and clean


(Bash completed with no output)


The issue is 45M temporary vector allocations fragmenting the heap. Fix: use a reusable `thread_local` or stack-allocated buffer for entry IDs instead of creating/destroying vectors per cell:

138 GiB at 19:38 CPU time. Getting tight. The output buffers are growing large. Let me wait:


sleep 60 && sshpass -p 'elon-is-insane' ssh -o ProxyCommand="tailscale nc %h %p" -o StrictHostKeyChecking=no michtest@100.113.88.121 "grep -c 'Geo entry pipeline\|All_checked\|Total patch' /home/michtest/planet-patch-stream.log 2>/dev/null; ps aux | grep 'geocoder-patch planet' | grep -v grep | awk '{printf \"RSS: %.0f GiB\\n\", \$6/1024/1024}'" 2>&1

131 GiB — dropped from 138. Could be writing files (frees output buffers). Let me check:


sleep 30 && sshpass -p 'elon-is-insane' ssh -o ProxyCommand="tailscale nc %h %p" -o StrictHostKeyChecking=no michtest@100.113.88.121 "grep 'Geo entry\|Admin\|Total patch\|All_checked' /home/michtest/planet-patch-stream.log; ps aux | grep 'geocoder-patch planet' | grep -v grep | wc -l" 2>&1

The log file has the old killed message mixed in. The new process output isn't in this file — it might be writing to a different file descriptor. The nohup `>` should have truncated but the old content is still there. The issue: the command had `> planet-patch-stream.log 2>&1` in a nohup block — both old and new write to the same file.

Let me check if the new run completed by looking at the output dir:


sshpass -p 'elon-is-insane' ssh -o ProxyCommand="tailscale nc %h %p" -o StrictHostKeyChecking=no michtest@100.113.88.121 "ls -lh /home/michtest/patched-planet-stream/ 2>/dev/null && echo --- && ps aux | grep 'geocoder-patch' | grep -v grep | wc -l" 2>&1

The merge replay files are written (8 data files). The entry pipeline is still running — no geo_cells.bin, entries, or admin_cells yet. Process still alive (3). Memory must be in the streaming walk. Let me check:


sleep 60 && sshpass -p 'elon-is-insane' ssh -o ProxyCommand="tailscale nc %h %p" -o StrictHostKeyChecking=no michtest@100.113.88.121 "ls /home/michtest/patched-planet-stream/ | sort && echo --- && ps aux | grep 'geocoder-patch planet' | grep -v grep | awk '{printf \"RSS: %.0f GiB\\n\", \$6/1024/1024}'" 2>&1

152 GiB. Still no entry files. Getting very close to the limit:


sleep 30 && sshpass -p 'elon-is-insane' ssh -o ProxyCommand="tailscale nc %h %p" -o StrictHostKeyChecking=no michtest@100.113.88.121 "ls /home/michtest/patched-planet-stream/ | wc -l && ps aux | grep 'geocoder-patch planet' | grep -v grep | awk '{printf \"RSS: %.0f GiB  TIME: %s\\n\", \$6/1024/1024, \$10}'" 2>&1

160 GiB. Almost at the 174 GiB limit. The reusable buffer avoids new allocations but the output vectors (out_se, out_ae, out_ie, out_geo) keep growing. On planet these are ~700 MiB + 700 MiB + 30 MiB + 300 MiB = ~1.7 GiB for outputs. The 160 GiB is mostly from the old files + remap vectors + cell list + correction data all held simultaneously.

The real memory hogs are the `derived_id_remaps` which hold 4 vectors of 86M, 48M, 73K, 948K entries = (86M+48M) × 4 bytes = 536 MiB. Plus old files: geo_cells 300 MiB, 3 entry files ~1.5 GiB. Plus the cell list: 15M × 16 = 240 MiB. Plus correction data buffered from patch: 1.59M street corrections × ~16 bytes each = 25 MiB. That's ~2.7 GiB of real data.

The 160 GiB RSS is mostly from glibc memory fragmentation from all the merge replay phase allocations (building output vectors for each file) that were freed but not returned to OS.

Still at 8 files. Let me check if it was OOM killed:


sleep 60 && sshpass -p 'elon-is-insane' ssh -o ProxyCommand="tailscale nc %h %p" -o StrictHostKeyChecking=no michtest@100.113.88.121 "ls /home/michtest/patched-planet-stream/ | wc -l && ps aux | grep 'geocoder-patch planet' | grep -v grep | awk '{printf \"RSS: %.0f GiB  PID: %s\\n\", \$6/1024/1024, \$2}'" 2>&1

Check 1 min later


Process gone. 8 files = no entry files written. OOM killed during the streaming walk. The issue: glibc heap fragmentation from the merge replay phase (building 4 GiB of output data for merge files, then freeing it) leaves 100+ GiB of virtual memory mapped but unused. The streaming walk then can't allocate more.

The fix: free the merge replay memory more aggressively. After writing each merged file, the `output` vector is freed, but glibc doesn't return pages to OS. I need to use `malloc_trim(0)` after the merge phase to force page return:
