我的 ocsigen 服务器已经正常工作了一段时间,但就在我要向某人展示它时,它在启动时喷出这个,然后退出失败:
ocsigenserver.opt: ocsipersist:dbm: Cannot connect to Ocsidbm. Will continue without persistent session support. Error message is: Connection refused in connect() .Have a look at the logs to see if there is an error message from the Ocsidbm process.
ocsigenserver.opt: ocsigen:main: Fatal - While loading /home/unhammer/.opam/4.02.1/lib/ocsigenserver/extensions/ocsipersist-dbm.cmxs: Unix.Unix_error(Unix.ECONNREFUSED, "connect", "")
我该如何解决?
