Error description
Applications may hang waiting for console access. Even new telnet, ssh sessions etc may not work. However applications not using streams will continue to work. It is not a complete system hang but applications requiring console access will hang. Different threads in the dump or kdb will show the below stack: pvthread+1805600 STACK: [00054AA4]e_block_thread+000278 () [041AE498]_csq_acquire+000148 (??, ??)
