是否可以为CouchDB设置较低的堆大小，以防止出现“无法分配内存”错误？

Question

当我需要相对大的视图时，CouchDB（提交：b029b67）由于“内存不足”而死：

这是CouchDB关闭时我的RAM状态：

             total       used       free     shared    buffers     cached
Mem:       4148228    1048880    3099348      18412      10048     834928

Swap:      7812092      12944    7799148

这是./etc/local.ini（我发现相关）：

[couchdb]
os_process_timeout = 240000

[query_server_config]
os_process_limit = 130000

CouchDB需要如此数量的RAM是否正常，还是我可以更改的配置有误？
