Problem IT30471
|
Status: Closed |
SOCSSLLST THREAD CAN BLOCK FOREVER DURING ACCEPT OF CLIENT CONNECTION, WAITING FOR RESPONSE FROM CLIENT
|
| product: |
INFORMIX SERVER / 5725A3900 / B70 - IDS 11.70 |
| Problem description: |
During connection setup for ssl connections there appears to be
some needed back and forth between the client and server. As
currently written, during the accept, the socssllst thread can
block forever while waiting for some response from the client,
which, if for some reason doesn't come, prevents further ssl
connections from being made for that listener thread's port.
The stack trace and state of the socssllst thread would look
like this:
