Joshua Bronson commented on COUCHDB-275:
----------------------------------------
Though the patch prevented the term_to_binary snippet from crashing Erlang,
compacting still caused a crash. I had gdb attached while it happened but it
didn't help:
# gdb program `pidof beam.smp`
...
(gdb) continue
Continuing.
[hours pass while compaction progresses]
Apache CouchDB crashed, restarting in 3 seconds.
Program terminated with signal SIGKILL, Killed.
The program no longer exists.
(gdb) bt
No stack.
(gdb) # d'oh
For some reason it didn't catch Erlang in the act of crashing so there was no
opportunity to get a backtrace.
Using ulimit to increase stack size for now.
