正常运行的ssdb突然出现只能读取,不能写入的问题,然后过了一会也无法读取了

报错:./var/data/3548640.ldb: Bad file descriptor 配置文件: work_dir = ./var pidfile = ./var/ssdb.pid server: ip: 0.0.0.0 port: 6379 # bind to public ip #ip: 0.0.0.0 format: allow|deny: all|ip_prefix # multiple allows or denys is supported deny: all allow: 127.0.0.1 allow: 192.168 # auth password must be at least 32 characters auth: very-strong-password readonly: yes # in ms, to log slowlog with WARN level slowlog_timeout: 5 replication: binlog: yes # Limit sync speed to *MB/s, -1: no limit sync_speed: -1 slaveof: # to identify a master even if it moved(ip, port changed) # if set to empty or not defined, ip: 0.0.0.0 id: svc_2 # sync|mirror, default is sync type: sync host: localhost port: 8889 logger: level: error output: ssdb.log.txt rotate: size: 100000 leveldb: # in MB cache_size: 1024 # in MB write_buffer_size: 1024 # in MB/s compaction_speed: 1000 # yes|no compression: yes
