ns_server process keeps crashing

Couchbase Server
1

couchbase 2.2 on gentoo linux, got 66G free mem

I found on my server that the “ns_server” process keep restarting

so the admin console can not communicate to all the bucket, so the 8091 port don’t work

and I found these message in error log:

sorry, It’s not correct

I found "portsigar " process is restarting all the time

and “/opt/couchbase/lib/ns_server/erlang/lib/ns_server/priv/i386-linux-godu” restarting the same time

and couchbase don’t write data to disk any more

I check couch_server log:

it’s full of this:

[couchdb:error,2014-12-10T14:45:35.555,ns_1@10.1.29.12:couch_server<0.22612.136>:couch_log:error:42]Unexpected message, restarting couch_server: {‘EXIT’,<0.24653.136>,

I assume as you’re running on Gentoo you’ve built from source. 2.2 is a pretty old release (with a number of issues fixed) so I’d first suggest upgrading to something more recent - either 2.5.1 (most recent 2.X) or the new 3.0.1 release.
