CB 3.0.1 Disk Space usage

Hi,
hopefully some one will be able to help me out, i am running into an issue where the OS (Windows) is running out of disk space. a particular bucket keeps filling up “C:\Program Files\Couchbase\Server\var\lib\couchbase\data\bucket1” for instance.

i have also noticed compaction failures in the info logs. just wondering if there is a known bug or another issue.

[ns_server:warn,2015-10-15T21:48:44.229,ns_1@#.#.#.#:<0.1181.383>:compaction_new_daemon:do_chain_compactors:612]Compactor for view Bucket1/_design/Bucket1/main (pid [{type,

{name,

undefined,
false,
false,
{daemon_config,
30,
131072}},
false,
{[{type,
bucket}]}]}}]) terminated unexpectedly: {badmatch,
none}

any help would be greatly appreciated.
