1902017-03-18T20:40:00 <sipa> OOM>
1912017-03-18T20:40:01 <sipa> ?
1922017-03-18T20:40:10 <adiabat> this is with dbcache=64 and mempool=32
1932017-03-18T20:40:28 <sipa> ouch
1942017-03-18T20:40:36 <sipa> how much ram?
1952017-03-18T20:40:49 <adiabat> I don't think it's OOM; I don't get any St9bad_alloc or anything like that
1962017-03-18T20:40:56 <adiabat> this is 1GB, a raspberry pi 2
1972017-03-18T20:41:18 <sipa> 0.14 will just exit in the case of an OOM
1982017-03-18T20:41:29 <adiabat> ok, could still be OOM
1992017-03-18T20:41:44 <adiabat> what debug logging should I enable to see this better?
2002017-03-18T20:42:00 <sipa> look at dmesg?
2012017-03-18T20:42:07 <sipa> ah, no

2042017-03-18T20:42:21 <adiabat> actually, yes!
2052017-03-18T20:42:25 <sipa> 0.14 will try to write to debug.log that it ran out of memory
2062017-03-18T20:42:30 <adiabat> Out of memory: Kill process 13720 (bitcoind) score 333 or sacrifice child
2072017-03-18T20:42:34 <sipa> ah
2082017-03-18T20:42:39 <sipa> 1 GB is very little
2092017-03-18T20:42:52 <adiabat> whole bunch of stuff in dmesg
2102017-03-18T20:43:05 <sipa> plus RPi loses some memory for the GPU
2112017-03-18T20:43:20 <adiabat> yeah, could set up swap I guess? This is testnet though... although I guess there's no difference :)
2122017-03-18T20:43:50 <sipa> swap would move it from crashing to unusably slow :)

2142017-03-18T20:44:15 <adiabat> well, perhaps, but it seems to last a day or two without swap
2152017-03-18T20:44:28 <adiabat> so maybe it would only use swap occasionally
2162017-03-18T20:44:38 <adiabat> I haven't actually used swap in linux for a long time though
2172017-03-18T20:45:37 <adiabat> super hack-y but I might just make a watchdog script that restarts it if it's dead
2182017-03-18T20:46:53 <btcdrak> the 2GB pine64 needs swap to run bitcoind remotely well.
2192017-03-18T20:47:45 <sipa> i'm trying to fix the memory peak during flush, but it seems nontrivial
2202017-03-18T20:48:01 <sipa> it's been worsened in 0.14 due to the borrowing of mempool

2222017-03-18T20:48:38 <gmaxwell> adiabat: that may just be another issue.

2242017-03-18T20:49:21 <gmaxwell> adiabat: can you run bitcoind inside gdb to see if you can learn more of the crash? gdb ./bitcoind <enter> then run -daemon=0 <enter>

2262017-03-18T20:49:58 <adiabat> gmaxwell: will run that and leave it; might take a while to crash
2272017-03-18T20:51:03 <gmaxwell> if it crashes, type "thread apply all bt" and save the couple screenfulls of output.
2282017-03-18T20:51:41 <adiabat> will do
2292017-03-18T20:51:42 *** mol is now known as moli
2302017-03-18T20:52:23 <adiabat> also wondering if it may be arm-specific; I think there are a decent number of testnet nodes on little VMs like digital ocean w/ 1GB
