Hello.
'pstree' is provided.
Here it is for now:
[simamura@web373 ~]$ pstree
?-+-httpd-+-httpd
| |-2*[httpd---13*[{httpd}]]
| `-httpd---12*[{httpd}]
`-httpd.worker-+-2*[httpd.worker---14*[{httpd.worker}]]
`-httpd.worker---6*[{httpd.worker}]
The problem is that I can't catch the situation with memory overflow. When
webfaction notifies me, all processes are killed already.
Is there any way to resolve this situation?
Thank you.
