[ruby-core:125234] [Ruby Bug#21990] [ruby-talk:444791] Regression: Ruby 4.0 constantly crashing
Issue #21990 has been reported by zenspider (Ryan Davis). ---------------------------------------- Bug #21990: [ruby-talk:444791] Regression: Ruby 4.0 constantly crashing https://bugs.ruby-lang.org/issues/21990 * Author: zenspider (Ryan Davis) * Status: Open * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN, 4.0: UNKNOWN ---------------------------------------- (Filed for a user on ruby-talk who can't get registered here for some reason) After upgrade to ruby 4.0, all our Rails applications are continuously crashing on different nodes at different locations. All the applications were running flawlessly for about a year with 4.0.0.p1 and 4.0.0.p2. Reverting to 4.0.0.p2 solves the issue. The behaviour is the same with 4.0.0 and 4.0.1, where 4.0.1 has the additional issue that the value of ulimit "unlimited" has been reduced below "EFBIG", so no coredumps can be written ("too big"). Bug reporting is not possible: After registering an account on https://bugs.ruby-lang.org/, one is requested to follow the instructions in an e-mail, but such e-mail is never sent; not even after repeatedly requesting it.

Issue #21990 has been updated by byroot (Jean Boussier). The C backtrace in the crash report seem bogus. Almost none of it make sense. Most of the functions on the stack can't possibly call each others. Using `gdb` or `lldb` to produce a backtrace from a core dump might help. ---------------------------------------- Bug #21990: [ruby-talk:444791] Regression: Ruby 4.0 constantly crashing https://bugs.ruby-lang.org/issues/21990#change-116971 * Author: zenspider (Ryan Davis) * Status: Open * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN, 4.0: UNKNOWN ---------------------------------------- (Filed for a user on ruby-talk who can't get registered here for some reason) After upgrade to ruby 4.0, all our Rails applications are continuously crashing on different nodes at different locations.

Issue #21990 has been updated by zenspider (Ryan Davis). Status changed from Open to Rejected Closing... I suspect this report is bogus. There doesn't seem to be any registration problems and @byroot pointed out that the C stack looks bogus. ---------------------------------------- Bug #21990: [ruby-talk:444791] Regression: Ruby 4.0 constantly crashing https://bugs.ruby-lang.org/issues/21990#change-117026 * Author: zenspider (Ryan Davis) * Status: Rejected * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN, 4.0: UNKNOWN ---------------------------------------- (Filed for a user on ruby-talk who can't get registered here for some reason) After upgrade to ruby 4.0, all our Rails applications are continuously crashing on different nodes at different locations. All the applications were running flawlessly for about a year with 4.0.0.p1 and 4.0.0.p2. Reverting to 4.0.0.p2 solves the issue. The behaviour is the same with 4.0.0 and 4.0.1, where 4.0.1 has the additional issue that the value of ulimit "unlimited" has been reduced below "EFBIG", so no coredumps can be written ("too big"). Bug reporting is not possible: After registering an account on https://bugs.ruby-lang.org/, one is requested to follow the instructions in an e-mail, but such e-mail is never sent; not even after repeatedly requesting it.
