ctype_ujis                     [ fail ]

Errors are (from /dev/shm/var-ps_row-132/log/mysqltest-time) :
mysqltest: Could not open connection 'default': 2013 Lost connection to MySQL server at 'sending authentication information', system error: 32
(the last lines may be the most important ones)

I downloaded the tree from pushbuild. It does not contain a core file. The logs have no suspicious entries. Only mysqltest.log has a copy of the above error message.

I am unsure if this is indeed a character set problem. It can also be an API or communications problem.

How to repeat:
See the pushbuild log.

Ingo, does the test still fail?
32 is the error code for "broken pipe". It happens when a connection is closed, either due to a timeout or a server restart.

No, it happened once only. So I guess it is/was a rare race condition. I would accept closing this bug with a reasoning which makes it plausible that this has been fixed together with other bug fixes.

Ingo, anything could have happened. I believe it is simply not practical to chase such a heisenbug that could have been caused by any environment error, starting from human intervention and ending up with an OS error condition such as out of disc space or file descriptor.
Let's get back to this when the problem re-occurs.
