Commented by: @hvlad firebird_3 dump is related with events processing firebird_av_1 is produced by 32-bit build which i don't have. |
Commented by: Sorien (sorien) here is your's 32bit version https://www.merkuris.sk/files/Firebird-3.0.4.33011-0_Win32.zip with pdb as i see on our end there is just simple query that is fetching users and permissions from our table in separate connection and database trigger RECREATE TRIGGER DISCONNECT_SHEDULER but app is not listening for event EVENT_SHEDULER and occasionally server will crash, i'll try to create simple demo but don't thing that it will be reproducible easily |
Commented by: @hvlad Could you test this patched build (Win64), please ? |
Commented by: Sorien (sorien) i have tried that version and there is still same server crash, if you need dump just let me know i'll try to remove that database trigger, it looks like its causing our problems and it's not so important |
Commented by: Sorien (sorien) disabling that trigger did not help crash dump (for your build http://ge.tt/8nrSJlq2) |
Commented by: @hvlad Another races and new build to test http://ge.tt/7wKaGpq2 |
Commented by: Sorien (sorien) still crashing dump https://www.merkuris.sk/files/firebird.exe_180731_084234.zip maybe it will help, for testing i'm force terminating our app during these queries https://gist.github.com/Sorien/558c028ee20157a3976b2c283f356a0b |
Commented by: @hvlad New build here: http://ge.tt/8P16bqq2 |
Commented by: Sorien (sorien) it seems to be harder to crash server https://www.merkuris.sk/files/firebird.exe_180801_084732.zip |
Commented by: @hvlad Could you also provide us with firebird.log, if it is not empy ? |
Commented by: Sorien (sorien) this shoud be from testing |
Commented by: @hvlad This build contains some extra logging : Please, remove (or clear) firebird.log before run this build and provide me with both memory dump and firebird.log on next crash |
Commented by: Sorien (sorien) after 2 hours of testing i'm not able crash that build, will try to find more testers and provide logs when it happens Edit: dump (firebird.log) is inside archive |
Commented by: @hvlad Seems that logging makes harder to reproduce the issue, sad. |
Commented by: Sorien (sorien) firebird.log is inside zip archive |
Commented by: @hvlad What archive ? ;) |
Commented by: Sorien (sorien) http://www.merkuris.sk/files/firebird.exe_180803_103833.zip (i edited my last post after server crashed) |
Commented by: @hvlad Thanks, log helped, but i need a bit more info A new build with more logging: http://ge.tt/6f5e2wq2 BTW, have you cleaned all INET errors from the firebird.log before put it into archive with dump ? |
Commented by: Sorien (sorien) that one was from my colleague, it was not changed in any way, on his machine he is able to reproduce it without killing our software |
Commented by: Sorien (sorien) after few tries server did not crashed but can't attach to db anymore and in firebird.log i have PC Tue Aug 07 11:04:01 2018 |
Commented by: @hvlad There should be much more messages in the log... |
Commented by: Sorien (sorien) here you are https://gist.github.com/Sorien/9027b757396e80818213a1c4062db54a |
Commented by: Sorien (sorien) and https://gist.github.com/Sorien/a2c435642a9d5954667a8eb87801cf5d (server slill not crashed) |
Commented by: @hvlad Found mine error, i'm sorry |
Commented by: Sorien (sorien) here is crash dump + log (for your last build) http://merkuris.sk/files/firebird.exe_180807_123834.zip in firebird.log i just replaced db name to FOO.fdb |
Commented by: Sorien (sorien) and one more http://merkuris.sk/files/firebird.exe_180807_135337.zip |
Commented by: @hvlad Thanks, looks like i found a bug reason. |
Commented by: Sorien (sorien) it looks good so far no crash, i'll test more and report back |
Commented by: @hvlad If there is no more issues, i going to commit patch and close the ticket. |

Commented by: Sorien (sorien) I can confirm there are no more such issues. May I ask if there are any plans to release 3.0.4 stable version anytime soon?, cause it fixes our stability issues and it's its i bit difficult to ask admins update to nightly :) |
