Subject [jira] [Updated] (THRIFT-4465) TNonblockingServer throwing THRIFT LOGGER: TConnection::workSocket(): THRIFT_EAGAIN (unavailable resources)
Date Sun, 21 Jan 2018 09:00:00 GMT

     [ https://issues.apache.org/jira/browse/THRIFT-4465?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Buğra Gedik updated THRIFT-4465:
--------------------------------
    Description: 
Once I upgraded to 0.11.0, I'm getting the following error occasionally:

THRIFT LOGGER: TConnection::workSocket(): THRIFT_EAGAIN (unavailable resources)

I tracked this to the following change: [https://github.com/apache/thrift/commit/808d143245f4f5c30600fab31cf9db854cbf5b48#diff-fe8fec8ec38ea35df64cfcc305e3ab08]
  
{code:java}
// Work the socket right away

- // workSocket();

+ workSocket();

{code}
While adding SSL support, @dthaluru has re-activated the above line. From my own testing,
this causes occasional THRIFT_EAGAIN exceptions. It seems like this is due to calling workSocket()
too early and the socket gets a read call in non-blocking mode before it has data.
