 (Too many open files)

 

这个问题经过分析,可能是系统打开的文件数超过最大限制造成的.

通过看bea最大打开文件数限制,发现操作系统没有限制.

[bea@sczyapp1]/bea #ulimit -a
time(seconds)        unlimited
file(blocks)         unlimited
data(kbytes)         unlimited
stack(kbytes)        4194304
memory(kbytes)       unlimited
coredump(blocks)     2097151
nofiles(descriptors) unlimited
[bea@sczyapp1]/bea #

------------------------------------

 

通过查询bea设置发现

/bea/weblogic81/common/bin/commEnv.sh中,设置了

resetFd

 

所以bea的最大打开文件数为默认的 1024

此问题只要注释掉resetFd,并重启服务器就可以解决.
