shell request failed on channel 0，error exec request failed on channel 0


问题可能是因为配置的limit导致的。


需要修改

故障现象 ：终端报错shell request failed on channel 0
故障原因 ：进程数达到限制，系统进程数太小，导致不能连接
+ C- x8 F  B0 e' m解决方案 ：修改/etc/security/limits.d/20-nproc.conf中

7 ^, k5 r- o# e" n( e8 dsoft nproc 4096
0 ~, @* f3 S0 q/ p$ `) E% Znproc的值和指定用户在/etc/security/limits.conf中nproc的限定值
