> What was the problem with R3.14.8?

Mantis 232:

A non-preemptive mode client that does not idle
in ca_pend_event and relies instead on ca_poll
or ca_pend_event with a very short delay may not
reconnect. The problem wasnt easily reproduced
on Windows or Solaris but may occur more frequently
on Linux.

The vulnerability in the source code appears to
also be in releases before R3.14.8, but may have been
influenced by thread scheduling timing differences
to occur more often in R3.14.8.

Sorry about any inconvenience this may have caused.
