[5/10/17 2:38:12:697 EDT] 000090b7 SystemErr R Caused by: java.io.FileNotFoundException: /opt/IBM/WebSphere/AppServer/profiles/AppSrv01/installedApps/appsrv01Cell01/bcsa_war.ear/bcsa.war/medias/9c5bbab96a3843db9fdcc94e8ef928dc/f66642f4555dc9e701555deaea00000d_SCORM/content/course/sco05/end.swf (Too many open files)
报出：Too many open files错误。
使用ulimit -a命令查看配置信息：
[root@appsrv01 server01]# ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 135168 max locked memory (kbytes, -l) 32 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 10240 cpu time (seconds, -t) unlimited max user processes (-u) 135168 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited
发现open files参数配置为1024，修改为65535。
修改/etc/profile配置文件，在该文件中追加“ulimit -n 65535”
重新登录后查看最新配置：
[root@appsrv01 bin]# ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 135168 max locked memory (kbytes, -l) 32 max memory size (kbytes, -m) unlimited open files (-n) 65535 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 10240 cpu time (seconds, -t) unlimited max user processes (-u) 135168 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited
