Description
Seeing a similar thing happening on customer case CS0122589, but with different stack trace, where
Write to Client DCB 10.10.130.24 in state DCB_STATE_POLLING failed: 14, Bad address
followed by
double free or corruption (out)
leads to an abort() call first, followed by a segfault during signal handling.
This is happening repeatedly on two maxcale instances, sometimes even right after maxscale process restart.
