Hello,<br>
<br>
the first frames of the backtrace don't have the symbol table, do
have other core files from where you can extract the bt full?<br>
<br>
Also, 4.2.3 is old in its series, newer versions in branch 4.2 were
released. Can you update the latest version in branch 4.2 and
reproduce again? That will rule out is not a side effect of an issue
fixed after 4.2.3. You don't need to change anything in config or
database, just grab the latest sources from branch 4.3 and install
over the old binaries.<br>
<br>
Cheers,<br>
Daniel<br>
