[Bug-mailfromd] How to handle defunct processes?

[Mehmet Avcioglu <mehmet@xxxxxxxxxxxxx>]

Hello,

I am using the below function to lookup items from postfix hash tables, but seeing a number of defunct postmap processes. Is there a better way to handle this?

Thanks

func get_postfix_map(string query, string table)
    returns string
do
    number fd
    string cmd "/sbin/postmap -q %query /etc/postfix/%table"

    set fd open("|&2>null: %cmd")
    catch e_eof
    do
      	return ""
    done
    return getline(fd)
done
