Hopefully these issues have been taken care of in later releases - if not, let us know on those mailing list threads and/or Jira issues and we'll have another look. > > I don't know if got this already but for generating core dumps you have to > prepare your system.

For example, RHEL (/CentOS/Rocky) has the "abrt" daemon which, when installed and active, can handle core dumps and collect those and other information into a central location to aide in bug reporting. Some distributions, like you point out, disable core dumps by default and they have to be explicitly enabled. > > I'm really keen on hearing if the core dump problems are solved somewhen > since I experienced core dumps of guacd in different connections not only > what is discussed here.

I'd just suggest you track those on the existing conversations and/or bug reports, and update appropriately. In the cases where we cannot reproduce them ourselves we're relying on the information provided to determine if they are in Guacamole or some other system component. > > Also intresting to hear to rebuild the FreeRDP library - did it help? > At this point, the only time we're providing this as an alternative is with the issue with _aligned_recalloc(), and it isn't just rebuilding the library, it's building a newer version that does not contain the bug that causes the segfault. -Nick --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
