Java ps utility size 0
Hi all,

The other day I had a strange behavior with a Netra T2000 with Solaris 10.

When I tryied to run the ps utility it showed no output. Checking the /usr/bin I found that the size of ps is zero. Also other utilities like ptree, pstack also had size 0. Smilie

I copied the ps from another identical server and the everything came back to normal. All files had normal sizes and the utilities returned the expected output.Smilie

Can anyone have an explanation for this behavior?

Regards,
Cristian

ps, ptree, pstack and several dozens of other commands are a single isaexec based binary which call the real expected command located elsewhere. Someone overwrote one of these hardlinks with an empty file thus breaking all of them. Restoring one file was enough for all other programs to work.
