問題描述
Weblogic應用啓動後，在某個節點，root用戶切換到weblogic用戶報如下錯誤：
bash: fork: Resource temporarily unavailable
問題分析：
從錯誤的字面意思可以看到臨時資源不足
查看內存充足
查看用戶進程
ps -ef | wc –l
ps ux | wc -l
ulimit -u
查看用戶限制
su – weblogic(報錯，無需理會等會兒)
ulimit –a

解決方法
修改操作系統的資源配置：
su – root
vi /etc/security/limits.conf
增加如下內容
weblogic soft nproc 2047
weblogic hard nproc 16384
weblogic soft nofile 1024
weblogic hard nofile 65536
su – weblogic(此時應該不會報錯了)
ulimit –a
