Solaris 10 Server refuse to connect :wall:
fork: Resource temporarily unavailable , server unexpectedly unavailable network connection , refuse error, disconnect message, fatal error type2, (protocol error type2)

Issue has been resolved after taken few steps :b:
First of all need to check whether your server's virtual memory is busy or not with specific logs like, sendmail , logs, var messages and any other application logs.
Need to login through console/ALOM
you can use this command to check specific process in count

 # ps -ef |grep sendmail | wc -l
>If count numbers are more then
>Disable sendmail
#svcs disable sendmail
Then
# cd /va/spool/sendmail
#rm * OR 
# kill -9 `ps -ef |grep sendmail |awk {'print $2'}`

as well as also remove
mailq, mail.local and qmail too
Once you sure all kind of above logs and mail are removed then check server will allow to login :b:

I found it handy to have several xterms already running, so I could deal with a full swap device, even if I had to sacrifice them using 'exec' when I could not create new processes using fork. As not-root, I could 'exec rm -rf /tmp' relatively harmlessly and give back some tmp space as swap on Solaris, where tmp is mounted on swap.
