------------------------


I found the reason of the qmaster hard descriptor limit is set to 1024 message
appears in messages file and testsuite than never finish.

It was because, while from qmaster it is possible to login to all host and this
ability is checked by testsuite, from some hosts is not possible to login back
to qmaster without supplying credentials. It leads to infinite loop in testsuite
and in short term it consume all 1024 descriptor.

Please note, no core and no error is reported. There is infinite wait.

See the typical messages output.

We meanwhile have a testsuite (connection test) to find out such problems.
I think it is ok to close this issue.
