Hi,
I've just run into a new bug. I was running rpcbind with the -l flag,
and when I started Opera and it tried connecting to 127.0.0.1:111 to
begin the DNS resolution phase, rpcbind started fork()'ing and eating
up all resources.
After a few minutes, I could get this from `ps`:
root ~ # ps ax
PID TT STAT TIME COMMAND
0 ?? ZW 0:00.00 (rpcbind)
0 ?? ZW 0:00.00 (rpcbind)
0 ?? ZW 0:00.00 (rpcbind)
0 ?? ZW 0:00.00 (rpcbind)
0 ?? ZW 0:00.00 (rpcbind)
[snip]
11259 ?? S 0:00.03 rpcbind: logit (rpcbind)
11260 ?? S 0:00.03 rpcbind: logit (rpcbind)
11262 ?? S 0:00.03 rpcbind: logit (rpcbind)
11263 ?? S 0:00.02 rpcbind: logit (rpcbind)
11264 ?? S 0:00.02 rpcbind: logit (rpcbind)

and the box wouldn't respond until I finally got X killed and thus
Opera too.
