Hi Vladislav! I will try to crash it again =) This time i will run with --core-file, but i think it's something related with antivirus + innodb async calls, i'm not sure yet... i just started the server from command line after unzip of binary 32bits package, in other words, i was surprised about a crash with nothing running but now it's not happening :/ i know antivirus is a problem for async calls at windows, if i reproduce it, i will open a jira bug :) thanks for the --core-file parameter, i think i never used it before on windows
any news i will post again or create a jira bug :) thanks again :) 2013/9/16 Vladislav Vaintroub <[email protected]> > > > > -----Original Message----- > > From: Maria-developers [mailto:maria-developers- > > [email protected]] On Behalf Of Roberto > > Spadim > > Sent: Montag, 16.
