On our RHEL servers I've been noticing a lot of:
Failed to merge ...
{{badmatch,{error,system_limit}},[{bitcask,scan_key_files,3},{bitcask,'merge1',3},{bitcask_merge_worker,do_merge,1}]}
This is a RHEL 6 / Riak 1.0 test cluster which has Riak running as root. I
have not noticed this at all on our production 0.14.2 FreeBSD cluster.
My ulimit -a output is as follows:
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 127400
max locked memory (kbytes, -l) 64
max memory size (kbytes, -m) unlimited
open files (-n) 40560
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 10240
cpu time (seconds, -t) unlimited
max user processes (-u) 1024
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
An lsof -p shows open files of around 3 - 5k during the merge and about 1,300
post fail. Anybody have an idea what system limit I may be hitting?
Thanks!
TJ
